• Resetting the Microsoft Store will revert the Microsoft Store back to a clean installation state and remove any problems. This will wipe everything so be aware of that.
• Repairing the Microsoft Store will attempt to fix whatever problems there might be within the Store. But your data won’t be affected.

I recommend using the Repair option first, then checking to see if the problem has been solved. If you still get the same error message, use the Reset option.

To run either of these tools do the following:

• Press the Windows Key + I to open Settings.
• Next, go to Apps > Apps & Features, then scroll down until you get to the Microsoft Store entry.
• Now click the three dots to the right and select Advanced Options.
• Finally, scroll down and click Repair. Wait for the process to finish.
• If Repair doesn’t work repeat the steps and choose Reset.
