Windows 10’s Microsoft Store offers a convenient place to grab and automatically update apps, but it also tends to go wrong. If your store is throwing up “Windows Store cache may be damaged” errors in the troubleshooter, you’ll need to perform a Microsoft Store reset or clear the Windows Store cache to resume.

What is the Windows Store cache?

The Windows or Microsoft Store cache contains various pieces of data you’ve accumulated during your usage. This could include log files, thumbnails you downloaded, temporary download files, and more.

Sometimes, the data in this cache gets corrupted or otherwise conflicts with your Microsoft Store app. The easiest way to fix this is by resetting the Microsoft Store, which will also clear the cache.
