How to efficiently clean up disk space in windows 11?

Here's a practical, step-by-step guide to clean up disk space on Windows 11 without deleting any important files.

Uninstall Unused Apps and Optional Features

Some of the apps you never use might occupy a lot of disk space. You need to delete those apps from the PC in order to free up the disk space in Windows 11.

1. Settings → Apps → Installed apps.
2. Sort by size → Remove apps you no longer need.
3. Check Optional features and uninstall unused ones (like extra language packs, handwriting recognition for languages you don’t use).

Delete Old Windows Versions

If you've recently upgraded, you may have a Windows.old folder:

1. Open Disk Cleanup.
2. Select Previous Windows installation(s).
3. Delete (note: you can’t roll back after this).
