How to Fix the Low Disk Space Notification on Windows 10
As you know, Microsoft constantly releases new updates with the main goal of fixing bugs as well as deliver users with new and exciting features. However, there are times when the latest update comes with an unwanted bug. One of these bugs is an error message saying, “Low Disk Space. You are running out of disk space on Local Disk (G:). Click here to see if you can free space on this drive.” So if you have recently installed a Windows 10 update, then you’ll most likely see a completely new drive on your computer which will appear right after the installation of the update and you’ll also start seeing the aforementioned error message.
It gets irritating as this error message keeps on popping up even if you still have a lot of free space on your other drivers. Obviously, the main reason why this error message pops up all the time is the bug brought along by the Windows Update. This bug unhides the recovery partition drive and allocates it a drive letter which is why you are seeing a new drive in your computer. Thus, you can get rid of the pesky error message by simply removing the letter of the new drive. Just remember that you must not delete anything from the recovery partition drive nor format the drive. Formatting or deleting the recovery partition drive can heavily affect the recovery of Windows since the data on the drive is used by the Windows Recovery Environment or your system’s manufacturer.
A lot of users have reported that removing the drive letter has resolved the issue. And if you worry that removing the drive letter will delete the drive, you are mistaken. This solution is basically harmless and is proven effective to make the notifications go away.
Carefully follow the instructions below to get rid of the Low Disk Space notification by removing the drive letter.
Step 1: Tap the Windows key once.
Step 2: Next. In the Windows Start Search, type in “command prompt” and right-click on Command Prompt from the search results and select the “Run as administrator” option or you could simply tap Win + R keys and then input “cmd” and hit Enter to open Command Prompt.
Step 3: After opening Command Prompt, type in “diskpart” and tap Enter.
Step 4: Next, type in “list volume” and tap Enter. After that, you will see a list of drives.
Step 5: Take note of the letter associated with the newly created drive.
Step 6: Afterwards, type in “select volume <drive letter>” and tap Enter. Take note that you must replace the <drive letter> with the drive letter you’ve found in Step 5.
Step 7: Now type in “remove letter=<drive letter>” and then tap Enter. Once again, replace the <drive letter> with the letter you took note of in Step 5.
One of the most useful tools you can use to repair bad or corrupted sectors in the hard disk of your computer is the CHKDSK utility. However, there are also instances when this Disk Checking tool could encounter some issues and one of them is the error that states, “The type of the file system are RAW, CHKDSK is not available for RAW drives”.
This kind of issue is due to the RAW file format which is not recognized by the Windows operating system that you’ve installed which explains why you’re getting this error when running the CHKDSK utility. You can also encounter this error in case there is something wrong with the drive encryption.
To fix this error, you have to change the File System of the drive. How? Refer to the steps given below.
Step 1: The first thing you need to do is create a bootable Windows 10 media.

Step 5: Afterwards, type in either of the following commands to help you in either listing all the Disk connects or all the partitions on those disks formed.
diskpart or list volume
Step 6: Next, you need to select any of the two given commands below depending on the list you entered on the previous step.
select disk # or select volume #
Step 7: After you enter the command, it will select the Disk or the Partition you want to select. Now you have to type and enter the following command to clean your drive.

Reddit is one of the most popular websites in the world and how Microsoft is opening doors to everyone in its new store Reddit took a logical step and made a Progressive web application and placed it in it.
Being a Progressive web app makes it more familiar and feels like a home experience using it for a lot of Reddit users.
Reddit itself has a large community and active topics discussions all the time about anything. Bringing it to Windows as an application is, in my opinion, a great move since as an application it is independent, more light-weighted, and offering some other advantages specifically tied to being a standalone windows application.
Everyone familiar with and using the Reddit website will feel right at home in this app and you can start using it right away.

Windows comes with a built-in backup solution. However, if it failed because of an internal error, you will encounter an error message saying, “The backup application could not start due to an internal error, Server execution failed (0x80080005)”. When you get this kind of error, it means that it did not start and the process failed with a Server execution error. If you got this kind of error worries not for this post will guide you in fixing the problem in your Windows 10 computer.
The Windows Backup service is an excellent feature in Windows that only works on the NTFS file system and if you want to use this make sure that you have formatted your files system to NTFS. It is performed by the Volume Shadow Copy, all you have to do is right-click on any folder and if you see the “Previous versions” option, this means that a backup process runs from time to time and can bring back old files when needed.
To resolve the “The backup application could not start due to an internal error”, here are two suggestions you can check out.
Option 1 – Check if the Volume Shadow Copy service is running and restart it
The first thing you need to do is check if the Volume Shadow Copy service. To do that, refer to the following steps:
Click on Start and type “cmd” and right-click on Command Prompt from the search results.
Then select the “Run as administrator” option to open Command Prompt with admin privileges.
After that, type “net stop sdrsvc” and hit Enter to execute the command in stopping the Volume Shadow Copy service.
Next, type the “net start sdrsvc” command and hit Enter to start the service again.
Note: You can also restart the service using the Windows Services Manager.
In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
From there, look for the Volume Shadow Service (sdrsv) from the list of services. Its Startup type should be set to Manual by default.
Restart the service and if you don’t encounter any error while you turn it on, re-run the backup service and see if the backup process runs successfully.
Option 2 – Try to run the Volume Shadow Copy Service in a Clean Boot State
If the first option didn’t work and the service still keeps on failing even though the service is running, you can try putting your computer in a Clean Boot State and then try to run Windows Backup again.
Log onto your PC as an administrator.
Type in MSConfig in the Start Search to open the System Configuration utility.
From there, go to the General tab and click “Selective startup”.
Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
Next, click the Services tab and select the “Hide All Microsoft Services” check box.
Click Disable all.
Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
Now try to run the Volume Shadow Copy service again and see if the process goes smoothly.
Note: You might also want to delete all the files in the backup solution if you want to start fresh with the backup solution. Just go to C:/System/Volume/Information/Windows Backup and take ownership of the folder. After that, make sure to stop the Volume Shadow Copy service and then delete all the files inside it.

Many are upgrading their OS to Windows 10, however, it’s not always smooth sailing because users have been reportedly experiencing different bugs including Black Screen after a successful update.
One common issue in installing Windows 10 is the appearance of a black screen after installation. This usually occurs when the user restarts the computer. Initially, there will be a black screen only appearing on the monitor. There are also cases where a mouse cursor is present, while some cases have no cursor at all.
Not only that, it seemed that you’ve lost all your desktop icons when experiencing this bug.
Solution
Error Causes
Just like the other bugs experienced by Windows 10 users, booting to a black screen has reasons. Before you even try to look for the solution, you first have to determine the cause of the error, in this case, the error would be black screen when booting.
Error on external devices such as printer or mouse.
Having outdated display/video drivers that normally result in black screen when OS is updated.
If error messages are left unsolved, you may encounter other Windows 10 related issues such as error code 0xc0000142.
Further Information and Manual Repair
Before you even think of upgrading your OS to Windows 10, you need to know that there are specific system requirements and specifications to be able to successfully update your operating system.
A Microsoft DirectX 9 graphics device or later with WDDM 1.0 driver graphics card
800 x 600 display
A Microsoft account and Internet access.
There are more system requirements in order to use other certain Windows 10 features, but we’ll focus on solving your black screen problem in this article.
IMPORTANT NOTE: While it’s possible that you’ll be able to find the solution for your black screen during Windows 10 update, contacting the service of a professional technician or using an automated tool is advisable if you’re not confident in performing the methods to be discussed.

Hit the “Change settings that are currently unavailable.”
Make sure to unmark the checkbox button saying, “Turn on fast startup.”
Wondering if upgrading to Windows 11 will boost your gaming experience? We can’t give you a straightforward answer, sadly. But we can take you through the tweaks you can expect if you have all the right requirements and help you make a final decision.
Is Windows 11 good for gaming?
Essentially, the answer to this question is yes. Microsoft has definitely added a bunch of enhancements and features to its latest OS to give gamers the best possible experience. However, you have to keep in mind that this may not work out smoothly for every single user.
Whether you’ll be able to fully take advantage of the Windows 11 gaming features really depends on your setup. As expected, Windows 11 has more demanding system requirements than its predecessor.

So, unless your hardware can run the new OS comfortably, you might not be able to make the most of all these gaming perks. In that case, we recommend you first upgrade your hardware and then make the switch. Be prepared to be a little surprised by a few other interesting changes in comparison to Windows 10, though!
For some of the new gaming features to work, it’ll also be necessary for you to have an NVMe SSD and an HDR-compatible monitor. So let’s take a look at 4 big improvements you can expect if your setup is compatible.
Gaming enhancements on Windows 11
1. Enjoy faster loading speed with DirectStorage
For this powerful feature to work, you need a compatible graphics card and, as stated before, an NVMe SSD. It’s also important for your GPU to support the DirectX 12 graphics API at least. And since we’re on that subject, you’ll be happy to know that Windows 11 has also introduced a new version of the API called DirectX 12 Ultimate.
Now, what does DirectStorage do? It’s a new feature designed to make full use of the speedy storage of NVMe SSDs. It also transfers game data directly onto the graphics card, lightening the load on your CPU. Normally the CPU would have to decompress the data first, but DirectStorage helps bypass this. That’s how loading times are reduced and games run more smoothly.
2. Fully immerse yourself through Game Mode
Windows 11’s Game Mode is certainly a welcomed addition. When you turn on Game Mode, usage of background apps that aren’t essential to your game is reduced. This results in the game you’re running becoming a priority process. This way, it uses your hardware and system resources to the max. Ultimately, the Game Mode means less lag and higher frame rates so you can play undisturbed and fully enjoy your gaming session.
3. Vibrant visual experience thanks to AutoHDR
For this one you’ll absolutely need an HDR-compatible monitor. Basically, HDR (High Dynamic Range) means a wider range of contrasts and colors that can be displayed on a monitor.
Windows 10 has an HDR feature, but you have to turn it on and off manually (“Use HDR”). Plus, users have reported that, if left on, it results in an unappealing appearance of content other than movies and games.
Windows 11 fixes that problem with its AutoHDR feature. Toggling it results in the system automatically adjusting the color contrast, balance and brightness based on what you’re currently looking at. For gamers, this means vivid imagery in every single game, resulting in a supreme visual experience. You can check out Microsoft’s own video showcasing the power of AutoHDR.
Aside from AutoHDR, another way Windows 11 improves the visual aspect is through its support for refresh rates of up to 360Hz.
4. Xbox Game Pass & Game Bar
It’s no secret that Microsoft wants to integrate Windows and Xbox. We’ve seen some attempts with Windows 10, but they’re pretty wonky compared to the new OS.
Windows 11’s built-in Xbox Game Bar enables quite a few options all gamers desire. You can take screenshots and videos of your game and send them, for starters. Furthermore, you can use it to see audio settings and monitor your PC’s performance without having to leave the game or open the Task Manager.
Widgets are also a really cool part of the Game Bar. You can choose from a wide variety of widgets, such as Xbox Achievements, Spotify, Gallery, Xbox Social and more.
Moreover, the Xbox Game Pass has been streamlined on Windows 11. Game Pass is a subscription service that unlocks hundreds of awesome games and supports cloud streaming. Do keep in mind that the games are only unlocked for a certain period of time, as the selection rotates once in a while.
What can you do for a better gaming experience?
Windows 11 does offer tweaks that require zero input from you. However, there are a few things you can do manually to get even more out of your new OS while gaming.
Turn off enhanced pointer precision. Most games enhance precision by default, so having this feature on might interfere with that.
Make sure to select your high performance graphics card for each game. Go to Settings > Gaming > Game Mode and tap ‘Graphics’ from the ‘Related settings’ menu. Find the game you want to adjust, click on ‘Options’ and choose your high performance graphics card to be the default setting. While there, you can also turn on ‘Hardware-accelerated GPU scheduling’ at the top.
Disable unnecessary apps and programs. As long as they aren’t essential to running your game, they might take up valuable system resources, so disable them to make space for your gaming requirements.
Check for pending updates and install them. It’s well-known that out-of-date software causes bugs, latency and crashes. The same goes for your GPU drivers.
Use the High-performance power plan (Control Panel > Power Options > Additional plans) to maximize the use of resources for the best possible performance.
Summary
Windows 11 has done quite a bit for avid gamers. We hope your setup is compatible with all these new features and you can experience these enhancements ASAP!
There is a central location in Windows 10 that allows users to view all the notifications from its Action Center. Aside from viewing notifications, users can also manage them and take necessary actions in just one single place. Notifications in Windows 10 look similar to a message icon but can be at variance in function. However, recently, a number of users reported that even though they receive notifications about new actions but when opening them, they see nothing. In other words, the notification is false, and to fix this, read on as this post will provide you a couple of workarounds.
The Windows 10 Notifications and Action Center notification messages might show a mismatch. For instance, Windows 10 may say that you have some notifications but when you open Action Center, you find it empty and there are actually no notifications there. Take the case of the following screenshot, the Windows 10 Notification says that there are 6 new notifications available for viewing but the Action Center says otherwise.
Before you troubleshoot the problem, you might want to run System Restore especially if you’ve made some changes in your computer prior to this issue which might have messed with the Windows 10 Notifications and Action Center. To perform System Restore, refer to these steps:
First, press the Win + R keys to open the Run dialog box.
After that, type in “sysdm.cpl” in the field and tap Enter.
Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
If the problem wasn’t fixed and you’re still getting false notifications, you might want to troubleshoot the problem further using the options given below.
Option 1 – via Windows PowerShell
In the Start search, type “PowerShell” in the field and hit Enter to pull up the Windows PowerShell window.
Next, copy and paste this command and hit Enter to execute it: Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppxManifest.xml” -verbose }
After that, reboot your computer and check if the false notifications are now gone.
Option 2 – Try renaming the Usrclass.dat file
DAT errors like the ones that are associated with the Usrclass.dat file, most likely occur during computer startup, program startup, or while you try to use a specific function in your program. Even so, it can easily be fixed. How? Refer to the given steps below.
Tap the Win + R keys to open the Run dialog box.
Then type %localappdata%MicrosoftWindows and hit Enter to get to the location of the UsrClass.dat file.
After that, look for a file named UsrClass.dat and once you’ve found it, right-click on it and select the Rename option.
Now rename the file to UsrClass.old.dat and then restart your computer and see if the problem is now fixed or not.
