See what's using the space
Open Settings → System → Storage. Windows shows how much space apps, temporary files and documents are using.
Clear temporary files
In Settings → System → Storage → Temporary files, tick the items you want to remove and click Remove files. Leave “Downloads” unticked unless you have checked that folder first.
Turn on Storage Sense
In Settings → System → Storage, switch on Storage Sense so Windows clears old temporary files and the Recycle Bin automatically.
Run Disk Cleanup for system files
Search for Disk Cleanup, run it, then click “Clean up system files”. After a big Windows update, this can free several GB of old update files.
Empty the Recycle Bin
Files you delete stay in the Recycle Bin until you empty it. Check it first, then right-click it and choose Empty Recycle Bin.
Uninstall programs you don't use
Go to Settings → Apps → Installed apps, sort by size, and uninstall programs and games you no longer need.
Move photos and videos
Large photo and video folders are often the biggest users. Move them to an external drive or cloud storage — and keep a backup.

Questions
Is it safe to delete temporary files?
Yes — the Temporary files option in Settings and Disk Cleanup only remove files Windows doesn't need. Avoid deleting files from the Windows folder by hand.
How much free space should I keep?
Try to keep at least 15–20% of the drive free so Windows can update and run smoothly.
