How to clear computer cache on Windows 11?

If you want computer cache cleaning software for Windows 11 mainly to reclaim space (especially browser cache) on Windows 11, these three are the most practical picks, just keep them focused on junk/cache/temp files and ignore any “registry cleaning/driver updater” extras.

Microsoft PC Manager

This is Microsoft’s own lightweight “maintenance” app, so it tends to be the least risky for beginners. Its cleanup features are designed around removing junk files, including browser + application caches, and it also has one-click “health check/boost” style options. If you want something simple that feels “Windows-native,” this is the easiest place to start.

BleachBit (free, open-source)

BleachBit is one of the best software for clearing computer cache on Windows 11 and Windows 10. It can clear cache, cookies, history, temp files, logs, and lots of app leftovers, and it supports cleaning many applications (including major browsers). The big advantage is control—you can see exactly what categories it will delete before you run it—so it’s great when browser cache has exploded and you want a thorough, transparent cleanup.

Wise Disk Cleaner (free, beginner-friendly)
Wise Disk Cleaner focuses on freeing disk space by cleaning useless/outdated junk files plus browser traces (cache/cookies/history), and it’s very “click-and-go.” It’s a nice middle ground if you want more cleaning coverage than PC Manager but don’t want to think through lots of checkboxes like BleachBit. During install, pay attention and decline any optional bundled offers.

If your goal is freeing space from cache (especially browser cache) on Windows 11, Microsoft PC Manager is the safest set-and-forget option because it’s built for Windows and includes storage cleanup tools.

If you want the most control and the deepest cache cleanup across many apps, BleachBit is the strongest pick, just use Preview first and only tick cache/temp categories.  And if you prefer a simple, beginner-friendly cleaner that targets browser traces + junk files, Wise Disk Cleaner is an easy middle-ground (just be careful during installation and avoid any bundled extras).
