Windows 10 Cumulative Updates Aren't Installing: How to Fix?

A Windows 10 Cumulative Update is a collection of more than one updates. These cumulative updates contain all the new and previously released fixes. The good thing about these cumulative updates is that they don't duplicate any installed update. When a new update package is available for Windows 10 then only those files will be downloaded that aren't installed.

Windows 10 users have been facing a serious issue with these cumulative updates. Most of them weren't able to install a single Windows 10 quality update since December 2017. Even if you download the package from Microsoft update catalog and install it manually then it will not install at any cost.

I remember Microsoft released some dangerous Windows 10 updates in the previous month including KB4056892 (16299.192), KB4074588, and KB4058258 (16299.214)KB4056892 broke my Windows 10 PC and dropped the system in an unbootable state. The computer started but was unable to go past the Windows 10 logo. It returned an error stating "Your PC didn't start correctly" every time I switched it on. These cumulative updates returned error codes which are 0x80073715, 0x80070bc2, and 0x80070422. However, a Microsoft patch was released later.

So, what could be the problem with these cumulative updates? I don't have an exact answer for this but running the Windows update troubleshooter notified me a serious error known as 'Windows Update Database Corruption Error'. To repair the database I tried the DISM tool and the System File Checker (SFC /scannow) tool. But none of these tools fixed the problem. Then I decided to do a clean install of Windows 10 which worked with one cumulative update only. Even a clean install didn't fix the problem.

The only solution to this Windows update problem is to clean install Windows 10 without reusing the old 'System Reserved' partition for a new and clean installation. During a second clean installation round, I deleted the C:\ drive partition and the 'System Reserved' partition. 

Windows 10 Cumulative Updates Aren't Installing: A Permanent Fix As Of Now

To prevent any data loss situation always make sure that you have multiple copies of your data stored on your computer. You can use external hard drives. We recommend WD My Passport Ultra.

  • To do a clean install of Windows 10 you should be having a bootable USB. 
  • Always check the partitioning style of your current Windows 10 installation before doing a clean install. If your computer is using a GPT partition style then making a bootable USB with MBR partitioning style would be illogical.
  • To check the partition style. Type the following command at the command prompt.
diskpart <hit enter>
list disk <hit enter>
If under the 'Gpt' field you don't see any * (asterisk) then your computer's partition style is MBR otherwise GPT.
  • Now after knowing the partition style go on creating a bootable Windows 10 USB. Read this article - create a bootable USB Windows 10 with MBR or GPT.
  • After creating the bootable USB restart your computer and go to BIOS settings. In BIOS change the boot order and select the USB to boot from. Exit the BIOS.
  • When the BIOS boots the USB it will ask you to press any key to load the Windows 10 installation files. That's it now go on installing the software.

  • During the setup, Windows will ask you where to install the new OS. This is the most important part.
  • Here the disk partitions are labeled 0, 1, 2 and not C:\, D:\, or E:\. So be careful while formatting the right partition.
  • To identify the C:\ partition in the Windows setup it is always better to note its size and free space before installation.
  • You can get the drive info by right clicking the C:\ drive partition and checking 'Properties' in 'My PC'.
  • This will help us identify which is drive C:\ partition by checking its size and free space. So be careful in this.
  • Now select the C:\ partition after identifying it and delete it. Also, delete the 'System Reserved' partition.
  • Now create a new C:\ partition with all the unallocated space (including the System partition space).
  • After creating the new C:\ partition there would be no 'System Reserved' partition. But don't worry Windows 10 will automatically create a new 'System Reserved' partition on installation.
  • Start the installation and wait till it finishes.
After complete installation, check for Windows updates and let Windows install updates automatically. After this clean install, I hope all the latest cumulative updates will install on your Windows 10 PC as they are working fine on mine.

Amazon Prime Music Debuts In India: Prime Members Can Use For Free

The wait is over and Amazon has finally launched its Prime Music service in India. The Amazon Prime Music is now available in 46 countries including the US and India. The good news is that if you are a prime member then you can use it for free with your Amazon Prime subscription. You can not only use it on your android phone but also on iOS, Mac, Windows, and the Web. If you are an Amazon shopper then you don't need to download any other online music streaming app because the prime music has over 2 million songs and prime members don't need to pay for it.
I was eagerly waiting for Amazon Prime Music for a long time and had previously tried Wynk Music and Jio Music. But Wynk run annoying ads that sometimes degrades the user experience. On the other hand, Jio Music is free to use and ad-free but isn't available on PC/Mac. Amazon Prime Music is completely ad-free because it comes along with Amazon Prime subscription which can be purchased for 499₹ Rupees per year and is available to download for Android, iOS, Windows, and Mac OS. Amazon Prime is now one subscription service with three benefits (shopping, video, and music). It is cheaper than Wynk music which costs around 1200₹ per year.

How to Download Amazon Prime Music on Android

  • Download the Amazon Music APK from this Google Play Store link
  • Install and open it. During the initial setup, you will be asked to choose the language for your songs. You can select multiple languages.
amazon music india launch
The Amazon Music app is a music player app for Android which lets you create song playlists, search for music on the cloud, and download your favorite music to listen to it later. The app will also show your music files (songs) that are stored on your phone. There is a problem with Amazon Music if you have call recordings or voice recordings saved on the device. As these recordings will show up in the Amazon Music app. Since these recordings shouldn't be visible in the app so we have to hide them. To hide any unnecessary audio file put a '.nomedia' file in its folder. Copy and paste this '.nomedia' file in every folder which has voice recordings.

How to Download Amazon Prime Music on Mac/Windows 10

  • Download and install the Amazon Music from this link.
  • Click the 'Mac & PC' download link. Clicking the link will automatically download the installer for the OS that you are using.
  • After installing the software just sign in with your Amazon account with prime membership and start using the Amazon Music for free.
  • After opening the player app. Click your name at the top and click 'Settings'.
  • In 'General' click 'Music Preferences' and select different languages for songs.
  • Click 'Advanced' and select the 'Audio Quality'. But keeping the quality set to auto will save data.

How to Use Amazon Prime Music on The Web

  • Go to and choose your country.
  • After selecting the country sign in with your account details.
  • After signing in the web player start using it. The Amazon Music Web player looks like this below.

The only thing you may not like about Amazon Music is that it is not free. One should be an Amazon Prime member to use this. In India, this membership can be bought for 499₹ per year. The prime membership gives three benefits (priority shopping, video, and music). So taking this membership is far much better than buying other online video and music streaming services separately like NetFlix or Spotify unlimited.

The Cheapest Paid Alternative To Windows Movie Maker 2018

Microsoft just retired their Windows Live Movie Maker on January 17, 2017, and it is not available to download by any means. If somehow you get the executable file of Windows Movie Maker then it will not install on Windows 10. However, it may still work on Windows 7 but will not get any Microsoft support. If you were previously using Windows Movie Maker then you might be wanting it to work on Windows 10. And for this, you may download the Windows Movie Maker setup file from third-party sites. But I suggest not to do this because that file may contain malicious code which can harm your computer and files.

There are many free video editing software available on the internet. And some of them resembles the Windows Movie Maker. An example of this is a VideoPad video editor. Some other free alternatives to Windows Live Movie Maker are Shotcut, VSDC free video editor, and Avidemux. But a free video editor does come with some limitations.

Some of them will put their watermark in your videos. Some of them will not let you convert videos to Full HD or 4K. And mostly free video editors don't provide the essential video editing tools which are required to produce a meaningful video. If somehow free video editors provide you full features then they will be limited in some way and you will be asked to upgrade the software by paying money.

So why wasting your precious time behind free video editors when you can get the full-featured video editor at a dirt cheap price with a lifetime license. If you are affected by the Microsoft's decision of retiring the Windows Movie Maker then this article will benefit you. In this article, we are providing you the cheapest paid alternative to Windows Movie Maker 2018.

This cheapest paid Windows Movie Maker alternative is Movavi Video Editor 14 Plus. Besides knowing the useful features of a particular software most users will always quote the price as a 'cons'. But after reading this article your views will be in the favor of this paid software as you can have it at a dirt cheap price with a lifetime license.

Features Of Movavi Video Editor 14 Plus

1. Object Animation: With this feature, you can animate objects and turn them into a moving animation by using keyframes. Object animation is a useful feature that is needed to animate clipart themed videos. Windows Movie Maker didn't have this feature.

2. Green Screen Video: You may have seen many videos on YouTube or TV where the actors are shot against the green screen that later is replaced by burning cars, collapsing skyscrapers, or landscapes of astonishing beauty. This is also known as chroma key effect. Just shoot your video against a solid green background and use Movavi Video Editor to replace the background with the movie or video of your choice.

3. Picture in Picture (Split screen video): Showing multiple videos (side-by-side) on the same screen is an essential feature that wasn't supported by the Windows Movie Maker. With Movavi you can split the screen between two videos and also choose or delete the audio from the videos. You can place many videos on the same screen.

4. Built-in Media: Movavi Video Editor Plus has built-in media. It has 16 new video clips, 86 themed stickers and 22 new music tracks. So it is easy to put the background music in your videos without taking care of the copyrights if you are sharing them on YouTube.

5. Cut, Trim, Rotate, Join Videos: You can cut, trim, rotate, and join multiple videos together.

6. Callouts: During a video, you may need to highlight something on the screen with an arrow or an animated circle. For this purpose, callouts can be used to highlight or point towards important information in the video.

7. Highlight and Conceal: If you want to blur out faces or hide parts of a video and then use the conceal feature. But the only cons of this feature is that the hiding is not object tracking based. It only hides a fixed part on the screen. But it is still useful if the object is not moving.

8. Text Titles: Movavi Video Editor 14 Plus has lots of title texts. You can use them stylize texts in your video with animation. The texts can also be used to create intros for your brand. There are many text templates available and you can edit and design the text to fit your editing needs.

9. Countdown/Stopwatch Video Timer: Ever wondered how YouTube videos show stopwatch or countdown timers along with the playing videos? The timers feature wasn't available in the Windows Movie Maker and it is useful if you are making a video which requires an on-screen timer to record the time. The timer can be applied to any time-related video like counting the minutes of a booting computer on SSD. Counting the time of your gameplay videos.

10. Video Formats: You don't need to worry about video formats as Movavi supports almost every important video format that is mostly used by us like MP4, AVI, MPEG, MKV, DVD etc. You can export your video in 4K format also for UHD TVs and screens. All resolutions are supported and custom resolutions are also supported.

Awesome Video Shows Macro Videography Shot On a Smartphone

Macro videography is the art of shooting videos of very small objects. These objects are so small that they are sometimes not visible to our eyes. You can see such smaller objects with a convex lens or a camera with a zoom lens. Macro photography and videography require expensive equipment and telephoto lenses. But you can capture macro videos and photos with your smartphone by using a tiny DVD lens. Most Android smartphone cameras are capable of capturing videos at 4X or 8X digital zoom level clearly. At this zoom level, the videos look like if they were shot using macro filming techniques. The video is not actually a macro video but looks similar to it.

So, we used a Moto G4 Plus for this purpose which has a 16 MP PDAF camera. There is a big problem with Moto G4 Plus camera's glass cover as it gets scratched easily. Over time the camera glass gets scratched to a level which makes the camera blurry. The camera cannot even focus on objects and lose all its performance. While shooting a photo or a video you will only see blurred images and faded colors.

So, to restore the Moto G4 Plus camera's original performance we removed the glass cover and shot the video directly through the 16 MP camera sensor. Without any glass, in front of it, the camera takes very sharp photos and captures natural colors. If your G4 Plus's camera glass is full of scratches then consider replacing it or remove it completely. We can use the camera without any glass protection but we have to cover it when not in use to protect it from dust. We will be creating a cover for it and teach you to remove and use the G4 Plus camera without glass protection in our next post. Till then enjoy the video shot while the glass cover was removed from the camera. Watch the video below.

So, what could the problem be? In this tutorial, we will tell you how to fix the problem 'bandicam not starting'.

Bandicam Not Opening In Windows 10

Bandicam Not Opening In Windows 10: The Main Reason

The main reason behind 'bandicam won't open' is related to desktop or laptop computers that have a dedicated Nvidia graphics chip. If you have installed Nvidia GPU drivers along with the GeForce experience (Nvidia game optimizer) software then it will create a conflict between GeForce experience and Bandicam. This is the main reason why Bandicam won't open or even start on Windows 10 computer which has Nvidia next GPU.

Bandicam Not Opening In Windows 10: How To Fix?

  • Uninstall your Nvidia GPU drivers and restart the PC.
  • Now open Bandicam to check whether it is opening or not.
  • If it opens and you are able to record the screen then the problem has been fixed.
  • If it still doesn't work then uninstall Visual C++ redistributable packages from your computer by going to 'Control Panel>All Control Panel Items>Programs and Features'.
  • Now this time Bandicam will run definitely. The problem has been fixed.
  • Now you just have to download and install Nvidia GPU drivers.

How to Download and Install Correct Nvidia Driver

  • From the 'Product Type' select your Nvidia GPU type.
  • Then select the 'Product Series'. Suppose if I am downloading drivers for GeForce 900 series then I will select GeForce 900. I won't be selecting GeForce 900M because it is for notebooks. So select the right product series, because 900 and 900M series have a different number of Nvidia GPUs. 
  • Then in 'Product' select the right Nvidia chip.
  • Click 'Operating System'. A list will open and then click 'Show all Operating Systems'. This will show 32-bit and 64-bit operating systems. Select the right operating system architecture.
  • Select the language if you want to change it from English. Then click 'SEARCH'.
  • A download page will open. Click 'Download' to start downloading the driver.
  • Once the driver gets downloaded open it and it will ask you to extract the driver files. Extract the files in C:\ drive.
  • Now right click on 'This PC' and select 'Properties'. Then open 'Device Manager'. Here look for a device without any driver. The Nvidia GPU may be listed as '3D Video Controller'.
  • Right click on it and select 'Update driver'. Then click 'Browse my computer for driver software'.
  • Now click 'Browse' and select this directory below.
  • Here do note that the 388.31 is the driver version and may be different if you have an older or a new Nvidia driver software package. Change this number with your Nvidia graphics software driver version which you have downloaded.
  • After selecting the directory click 'Next'. Wait till Windows 10 finish installing the Nvidia display driver.
  • You will be notified when the installation gets completed. It will take some time to install though.

Now you can use Bandicam and Nvidia gaming graphics without any conflict. So we have successfully fixed the problem of Bandicam not opening in Windows 10.

How and Why to Protect Your Eyes From Digital Eye Strain Caused by Blue Light

Digital Eye Strain sometimes referred to as Computer Vision Syndrome is a vision condition that results from continued looking on a computer screen without blinking your eyes. Due to the prolonged eye focusing on the computer screens, mobile phones screen, or tablet screens the focusing power of the eyes' lens gets impaired over time. If you heavily use computers and smartphones then you may experience eye problems like headaches, eye dryness, eye itchiness, sleeplessness, difficulty in getting up early in the morning, and burning sensation in the eyes.

All digital devices including computer monitors, smartphones, and tablet screens emit high energy blue light. Digital devices use blue light to brighten their screens thereby releasing high energy in form of blue light. Blue light has a short wavelength which means it has high energy and it is the only light ray after UV rays that can penetrate a human eye back to the retina.

Computer Vision Syndrome

However, not all blue light is bad for the eyes. Blue light between 380nm and 470nm is known as bad blue light while blue light between 470nm and 500nm is actually good for the eyes. This range of visible blue light is beneficial because it provides natural reflexes protecting eyes from light overexposure, and helps with the body’s circadian rhythms, and helps cognitive and memory function. But finally, too much of anything is not actually good for you.

Sun's Blue Light vs Blue Light Emitted By Digital Devices

You may be thinking that Sun also emits blue light then why it doesn't damage our eyes. The Sunlight is actually white light which consists of seven colors. These colors are collectively known as VIBGYOR (Violet, Indigo, Blue, Green, Yellow, Orange, and Red). These all colors make up the Sun's white light which also has blue light starting from 380nm. Besides having a bad blue light spectrum the Sun doesn't hurt our eyes much as compared to the digital devices.

The answer is simple, suppose you are playing cricket on a sunny day. As a fielder, you will see that all your teammates are standing at distant places on the field. So, in the cricket game, you just have to focus on the ball and your teammates. Most of the time a ball will be at different places and in the hands of different players. This distance can be more than 10 feet. So you are actually focussing on distant objects and the principle says that when you focus on a distant object your eye muscles will do it easily without getting strained.

Also, your eyes are constantly changing objects, as a result, the Sun's blue light. And because of dust particles and a large number of objects around us the Sun's blue light gets highly scattered. So the Sun's blue light has almost no effect on our eyes if it isn't a very hot day or you are not wandering in a desert while reading an offline or bookmarked version this article.

But the blue light emitted from the computer screens and smartphones is not the same as of the Sun's light. Blue light from the smartphone screen will not scatter just like the Sunlight does. And more amount of it will enter your eyes because the focusing distance is just mere inches and your eyes keep on focussing same object (like text) for a long time. As a result, your eye muscles will have to work harder to focus on the screen that is few inches away. This results in eye problems like dry eyes, itchy eyes, headaches, insomnia (difficulty in sleeping), and difficulty in waking up early in the morning.

So that was enough science to teach you the bad effects of blue light. Now we will see how can we block the blue light emitted by our computer screens, smartphones, and tablets.

How to Block Blue Light on Android

Android nearly holds 87.5% percent of the global smartphone market share. So, Android smartphones are more responsible for damaging our eyes by emitting blue light. You can download blue light filter apps from the Google Play Store. When you use your tablet or smartphone in the night then enable the filter to prevent blue light from damaging your eyes and disturbing the wake-sleep pattern of your body. Blue light makes the brain more active so if your eyes consume it at night then you will have trouble in sleeping. Here's a good article for using and installing a blue light filter on android.

Some smartphone manufacturers like Xiaomi and Huawei provide their own light filters as a part of the phone's OS. You can find this option in the display settings. For Xiaomi go to 'Settings>PERSONAL>Display>Reading mode'. For Huawei go to 'Settings>Display>Eye comfort'.

How to Block Blue Light on Windows 10

Windows 10 has a built-in blue light filter. This setting is known as 'Night light'. Go to 'Settings>System>Display'. Under 'Brightness and color' click 'Night light settings'. Then click 'Turn on now'. Adjust the color temperature that suits your eyes.

How to Block Blue Light on Mac OS

Even Apple's Mac OS has this built-in functionality and you can use it to protect your eyes. On Mac, this feature is known as 'Night Shift'. To open night shift on Mac, follow the steps below.
  • From the Apple menu, launch System Preferences.
  • Click on Displays.
  • Click on the Night Shift tab.

Adjust the color temperature between less warm and more warm. Set the color temperature to that value which doesn't hurt your eyes. I think slight warmer colors will be best for screen viewing.

Tips to Prevent Digital Eye Strain

A blue light filter is not enough to prevent the Digital Eye Strain. Besides using the filter you may feel pain or dryness in the eyes. So below are some tips to prevent the Digital Eye Strain or the Computer Vision Syndrome.
  • The top of the computer screen should be at the eye-level to make the viewing angle between 20 and 40 degrees. It should not be greater than 35 degrees. Avoid tilting the monitor screen.
  • Reduce the screen brightness when working for long hours.
  • Use the 20-20-20 rule. This means make your eyes focus on an object for 20 seconds which is 20 feet away every 20 minutes.
  • Keep your eyes blinking. Blinking the eyes will prevent dryness and overexposure to blue light. Blinking will force the eyes to refocus the objects.
  • Relax your eyes for at least 5 minutes every day by closing your eyes. Then make a clockwise circle by slowly rotating your eyes. The perform the same exercise in an anti-clockwise direction.
  • Walk out in Sunlight for at least 10 minutes and focus on distant objects.

Digital Eye Strain is a common problem that affects a large number of people worldwide. At present, it is not possible to imagine a world without our computers and smartphones. And prolonged screen viewing will definitely work out our eyes in a negative way. So take the responsibility of saving your eyes today from Computer Vision Syndrome and also let others know about it.

Windows 10 KB4074588 Fails To Install (0x80073715): Is There Any Fix Yet?

KB4074588 is the second cumulative update for Windows 10 that has been released by Microsoft recently. It is also known as February 2018 Security Update for Windows 10 devices. This cumulative update brings many fixes related to internet explorer and Microsoft Edge etc. But just like the January cumulative update KB4058258 the KB4074588 keeps on failing while installing. Since the start of 2018 Microsoft has only released two major security updates for Windows 10 and unfortunately, none of them install. These updates report error codes including 0x80073715, 0x80070bc2, and 0x80070422.

Windows 10 KB4074588 Fails To Install

Windows 10 downloads the cumulative update KB4074588 but when it comes to installation it fails completely. The KB4074588 installs 25% percent only then it fails completely. But other Windows 10 updates are installing normally without giving any error code. So why these cumulative security updates aren't working? Nobody has a correct answer. If KB4074588 fails to install on your computer then you may be advised to apply the following fixes.

  • Use system file checker to check for file integrity problems.
  • Use the DISM tool to replace the corrupted Windows 10 system files.
  • Reset the Windows 10 update agent by deleting the SoftwareDistribution folder and renaming the catroot2 folder.
  • Resetting the Windows 10 update agent is a time-consuming process as you will have to run several commands. Read this official tutorial.
  • Manually download the package the from Microsoft Update Catalog.
  • Disable .net framework 2.0
  • Uninstalling your antivirus software because according to Microsoft it may have a problem with a key in the registry. But most modern antiviruses have already set the required key in the registry.
  • Signing out of your Microsoft account and creating a local account to install the update.
But unfortunately, none of the above-mentioned fixes work. You will just waste your time by giving those non-working fixes a try.

On running the Windows Update troubleshooter the system reports a 'Potential Windows Update Database Error'. Now, in this case, you will be advised to reset the Windows update agent and re-register the BITS files. But nothing will fix this installation error.

And it is not the case with a single Windows 10 user but the same problem is being experienced by many users around the globe. So, is there any fix for this problem? Currently no and we can only wait for a Microsoft patch that will fix the issues related to cumulative updates because other Windows 10 updates are installing.

Without security updates, Windows 10 will soon become vulnerable. Because many users haven't managed to install the January Security Update KB4058258 and Microsoft released the February 2018 cumulative update without fixing the prior security patch. And I am sure that Microsoft will not consider it as a serious problem unless it is experienced by a large number of Windows 10 users.

There is no fix for Windows 10 cumulative updates that fail to install. But if you are concerned about your computer's security then you shouldn't be skipping any of the monthly cumulative security updates. The only way of installing these updates is to do a clean install of Windows 10. I have tried this method with an update KB4056892 that just broke my computer a month ago. However, there is no guarantee that a clean install would definitely fix this problem.

➜ Update #1

A clean install will fix this Windows update problem. But during a new Windows 10 installation you should also delete the old 'System Reserved' partition. Read this updated article.
