Open Settings → System → Storage → Temporary files, review the categories, then remove the items you do not need.
Step by Step
- Open Settings.
- Select System.
- Select Storage.
- Select Temporary files.
- Wait for Windows to calculate the categories.
- Review each category carefully.
- Select the items you want to remove.
- Choose Remove files.
If That Doesn't Work
- Downloads may appear as an optional category; do not select it unless you intend to delete downloaded files.
- Windows Update cleanup can take time and may remove files used to roll back an update.
