01.The Game Pass Nightmare
**Xbox Game Pass** in 2026 is an excellent service, but the Windows app still suffers from deep integration issues with the Microsoft Store. Often, a game won't download or the 'Install' button simply won't react. This happens due to failures in the **Gaming Services**, an invisible component that manages licenses and the installation of Microsoft games on your PC.
Don't do it Manually.

02.1. Resetting the Xbox App and Microsoft Store
The first step is to reset the local settings:
- Go to Settings > Apps > Installed apps.
- Search for 'Xbox' and click the three dots > Advanced options > Repair/Reset.
- Do the same with the 'Microsoft Store' app.
- Open CMD as Administrator and type
wsreset.exe. A black window will open and close by itself; this clears the store cache.
03.2. Reinstalling Gaming Services via PowerShell
Definitive Solution:
If the simple resets didn't work, we need to force the reinstallation of the download engine.
In PowerShell (Admin), paste this command to uninstall:
get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers
After that, paste this to open the official installation page:
start ms-windows-store://pdp/?productid=9MWPM2CQNLHN
Install Gaming Services again and restart your PC. This solves 99% of 'Download stuck at 0%' cases.
04.3. Region and Time Check
2026 Tip: The Microsoft Store is picky about location.
Check if your Windows has Set time automatically turned on and if the Region is set correctly to your country. If there is a mismatch between your PC's time and the server's real time, your Game Pass subscription authentication will fail, preventing any download from starting due to a "security error".
Don't do it Manually.
