Microsoft store for desktop issue

Question

1. You signed out of the Store
   • The Store can work without being signed in.
   • Some history information, app ownership info, and synchronization may disappear.
   • This is normal behavior.
2. Store cache got refreshed
   • Sometimes after signing out, resetting the Store, or a major update, the update history temporarily appears empty even though the apps are still installed.
3. 26H2 bug
   • Since you're on a very new 26H2 build, it's possible there's a regression affecting Store history display.
   • The key question is whether downloads and updates still work. OS Build 26300.971 butis26300.9550
   • 26300.971ms store problems after KB5127648 date 24october 2026

Answer 1

Hello Magas,

Could you clarify exactly what is no longer working in Microsoft Store?

Please provide:

• A screenshot showing the problem
• The exact OS build shown by winver
• The Windows Insider channel under Settings > Windows Update > Windows Insider Program
• Whether Microsoft Store can still download and update apps
• Whether signing back into Microsoft Store restores the missing information
• What happened immediately before the issue started

Build 26300.9550 corresponds to KB5124010, but Microsoft does not currently list missing Store history as a known issue for that update. Without the exact symptom and current build, it would be premature to conclude that this is a Windows 11 26H2 bug.
