If your Windows 10 computer feels sluggish or if you’re running low on storage space, clearing your cache can significantly improve performance. Caches store temporary files that help your system and apps load faster, but over time, they can accumulate and slow things down. This article explores how to clear cache on Windows 10, including different types like system, browser, and RAM caches.

Why Clear Cache on Windows 10?

Cache files are intended to speed up processes by storing frequently accessed data. However, when too much cache builds up, it can cause the opposite effect:

  • Slower performance
  • Application errors
  • Low disk space
  • System instability

Regular cache clearing is a simple yet effective way to maintain your PC’s health.

1. How to Clear Cache on Windows 10 Using Disk Cleanup

The built-in Disk Cleanup tool is one of the easiest ways to clear system cache:

  3. Click OK to allow the tool to calculate potential space savings.
  4. In the list, check Temporary files, Thumbnails, System created Windows Error Reporting, and other cache options.
  5. Click OK then Delete Files.
