Hi Pablo,
I understand how alarming this is, and you’re right to be concerned. Based on the description, it's likely that Windows component store / UWP package is broken. The Q&A Assist has actually pointed to the correct path, so I suggest you check out their suggestions. If they don't work and you have to get to reset PC, please try the reinstallation repair below first:
1 - Use built-in repair option
- Open Settings > System > Recovery > Fix problems using Windows Update
- Click Reinstall now > follow the onscreen instructions to reinstall Windows.
Disclaimer: This reinstallation can fix update issues without removing your files or applications. However, we always recommend that if you have important data, you should back it up.
2 - Perform an in-place upgrade
- Refer to Reinstall Windows with the installation media - Microsoft Support
- Navigate to the bottom of the page and expand In-place Upgrade.
- You can also check out the instructions from one of the Moderators here: How to run In-place upgrade in Windows 11 - Microsoft Q&A
Disclaimer: An in-place install or in-place upgrade will refresh your Windows files and operating system without removing files or applications. That being said, we always recommend that if you have important data, you should back it up before making large system changes.
3 - Reset PC from Recovery
- Power on the PC > force shutdown during boot 3 times to trigger recovery
- When in WinRE, choose Troubleshoot > Advanced options > Reset this PC
- Choose Keep my files > Local reinstall > Confirm and let it complete
Disclaimer: This allows you to keep your files, but your applications and settings will be removed.
As you can see the number 1 and 2 above (Reinstallation repairs) let you keep your files and apps, while Reset PC only keeps your files. However, if nothing works, you might need to perform a clean install to get your PC back into a working condition: Reinstall Windows with the installation media - Microsoft Support. This solution will unfortunately delete all your data.
