How to Clear Your PC’s Cache in Windows 10

Just like clearing your browser cache, when you clear a cache in Windows 10 it can improve performance, free up disk space, and increase stability. Today we’re going to show you how to clear your cache in Windows 10, focusing on four key areas: disk cache, DNS cache, Store cache, and Microsoft Store cache.

What is the cache in Windows 10?

The Windows 10 cache, or really collection of caches, are locations in which the operating system stores data so that it can access it faster in the future. For example, Windows might store file thumbnails in a cache so that it doesn’t have to generate them again every time you open File Explorer.

They can also store corrupted or incorrect files that slow down or cause issues on your PC. As a result, it’s good practice to clear caches in Windows 10 every now and then.

Here’s how to clear the computer cache in Windows 10:
