Microsoft store or you can say Windows 10 Store not working after the recent windows update? you are not alone a number of users complained that they’re unable to even load the store. Some others are unable to download or update apps from the Microsoft store.

Microsoft store not opening

If you are getting the problem while downloading or update store apps then the first thing we recommend to:

1. Check and make sure you have a working internet connection.
2. Temporarily disable antivirus and disconnect from VPN (If configured)
3. Signout from the Microsoft store, restart your PC. Now sign in again and check if the problem solved.
4. Press Windows + R, type wsreset and ok, this will reset Microsoft store and start the app normally.
5. Again Microsoft Store might not open if your computer’s date and time are inaccurate. This is because the Store checks to see if the time it tracks is in sync with your computer’s. So check and make sure your system date, time and region settings are correct.
