Check Windows updates, time and region, reset the Store cache, then repair or reset the Microsoft Store app if it still does not open.
1
Record how Microsoft Store fails
Before changing Microsoft Store, record whether the Store opens, downloads, signs in, or updates incorrectly plus the exact code, Windows version, time, region, and account. Keep the current state, exact message, and any recent change available so each result can be compared.
2
Separate a cache problem from one damaged app
Separate a stale Store cache, pending Windows update, incorrect time or region, account problem, and one damaged app package before resetting the Store.
3
Update Windows and check time
Install Windows updates and confirm date, time, time zone, and region are correct.
4
Reset the Store cache
Press Windows + R, enter wsreset.exe, and wait for the blank window to close and Microsoft Store to reopen.
5
Repair the app
Open Settings > Apps > Installed apps > Microsoft Store > Advanced options and choose Repair.
6
Reset only if needed
If Repair fails, choose Reset, reopen Microsoft Store, and sign in again.
7
Verify the result
Restart Windows, open Microsoft Store under the intended account, and install or update one small trusted app. Confirm the Store still opens after closing it once.
8
Troubleshoot Microsoft Store
If the same code returns, purchases are missing, organization policy blocks Store access, or several Windows apps fail together, stop broad resets and return to the last known state. Preserve the exact error, versions, device or account scope, and failed step before using the linked official support channel.
