What to do first
Confirm Windows time and updates, run the Store troubleshooter, reset its cache with wsreset, and use Settings > Apps > Installed apps to repair or reset the Store.
Windows apps
If Microsoft Store opens briefly, shows a blank window, or does nothing, start with reversible app and account checks before changing system permissions.
Quick answer
Confirm Windows time and updates, run the Store troubleshooter, reset its cache with wsreset, and use Settings > Apps > Installed apps to repair or reset the Store.
Why it happens
The Store depends on Windows services, account authentication, cache data, app registration, system time, and network access.
Step by step
Safety note
Protect important files before resets, driver removal, account changes, or recovery operations. If the symptom points to hardware, repeated software changes can make diagnosis harder.
No. wsreset clears the Microsoft Store cache and then opens the Store. It is a low-risk first step for cache-related problems.
Use Repair first. Reset is a later step because it clears the Store's local data and settings, but it does not reset Windows itself.
