Windows 10: Cannot install Xbox app on Windows 10 through Microsoft Store & KernalBase.dll errors

Earlier today I attempted to open the Xbox app and it crashed instantly on start-up. I opened the Event Viewer and found that the error was with my KernalBase.dll file. I attempted to fix the issue by running various commands in the CMD with elevated permissions. This included sfc /scannow and DISM.exe /Online /Cleanup-image /Restorehealth. Neither fixed the issue. I then ran the command regsvr32 KERNELBASE.dll and it gave me the error:" The module "KERNELBASE.dll" was loaded but the entry-point DllRegisterServer was not found.Make sure that "KERNELBASE.dll" is a valid DLL or OCX file and th

The Microsoft Store, and the Xbox app doesn't work!

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to launch Microsoft Store, Xbox app and GameBar. I’ll certainly help you with this issue.



However, please let us know:

• Do you receive any error message?
  
• Are you aware of any changes made to the computer recently?
  
• Which build version of Windows 10 are you using currently? To check type:
  winver in the search bar on the Taskbar and hit
  Enter.
  

Meanwhile, I would suggest you to refer the steps mentioned below:



For issues with launching Microsoft Store, I would suggest you to refer the steps mentioned in the article

Microsoft Store doesn't launch.



Method 1: Store app troubleshooter



I would suggest you to run the Store app troubleshooter and check. Refer the steps mentioned below:

1. Press Windows Logo key + I, to open Settings.
   
2. Click on Update & Security and select Troubleshoot from the left pane.
   
3. Scroll down, click on Windows Store apps and select Run the troubleshooter.
   
4. Follow the on-screen instructions.
   

Method 2: Re-register apps



If Store app troubleshooter doesn’t work, I would suggest you to try re-registering the apps using PowerShell. Refer the steps mentioned below:

1. Press Windows Logo key + X, and select
   Windows PowerShell (Admin).
   
2. Paste the following command and press Enter:
   Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
   
3. Once the process is complete, restart the computer and check.
   

Method 3: New user account



If re-registering the apps didn’t work, try creating a new user account and check if the issue persists. Refer the article
Create
a local user or administrator account in Windows 10



Let us know the results.

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”
