• Right-click on the Clock’s icon (bottom right corner) and select Change date and time settings.

• Check the time zone either and reset it if it’s not correct.
• After that, reboot your PC.

Option 5. Clear Windows Store cache

• Hold Windows icon key (bottom-left corner) and Press R at the same time.
• Type WSReset.exe in the Run dialogue and click OK.
