Hi, good day!
How long has it been stuck at 15%?
I recommend waiting an hour or two for the installation process to complete.
If the issue persists, please try the following methods below.
- If you have a third-party VPN or Antivirus installed, please try to temporarily uninstall it then check if the issue persists.
- Reset the Microsoft Store cache
Press the Windows Logo Key + R to open the Run dialog box,
type wsreset.exe -i
and then select OK.
Note:
A blank Command Prompt window will open, and after about ten seconds the window will close, and Microsoft Store will open automatically.
- Reset the Microsoft Store app
Press Start then search Microsoft Store
Right click it then select App settings
Click Terminate > Repair > Reset
- Re-register built-in apps and reinstall the Microsoft Store app
Press Windows key + X
Click and Run Windows PowerShell (Admin)
Copy and paste the command below then press Enter.
Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Restart your computer
