Hi,
Thank you for writing to Microsoft Community Forums.
I appreciate the efforts taken by you in resolving the issue. I understand that you are unable to install a
Theme on your computer. I’ll certainly assist you with this.
I have tried to install the Theme on my computer and was successfully able to install it. Ideally, after installing
the Theme, you can go to Start >> Settings >>
Personalization >> Themes and click on the Theme to apply it.
However, if you do not see the Theme in the Settings page, it could be possible that the Theme is not installed
properly. As you have already tried resetting Microsoft Store, I would suggest you to try re-registering it and see if that helps.
Refer the steps mentioned below:
-
Press
Windows + X keys together and click on
Windows PowerShell (Admin).
-
Now type in the command and hit
Enter: Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\\AppXManifest.xml”}
-
Restart the PC.
You can also create a new user account on the computer and check. Refer the article
Create
a local user or administrator account in Windows 10.
I see that you are on 1903 build. However, the latest release of Windows 10 is 1909. You may want to keep your
computer up to date and check. You can Get the Windows 10 November 2019 Update
Let us know how it goes. We will certainly assist you further.
