Free up disk space
Recover tens of GB cleanly.
- Settings → System → Storage → Cleanup recommendations: remove temporary files and old updates.
- Turn on "Storage Sense" for automatic cleanup.
- Classic Disk Cleanup, with "Clean up system files":
cleanmgr
- Shrink the Windows component store (administrator):
DISM /Online /Cleanup-Image /StartComponentCleanup
- Visualise what takes up space with WinDirStat (see "Recommended software").
⚠️ Never manually delete the C:\Windows\WinSxS folder.
