Step 3. You can see how much space you can use Disk Cleanup to free up, tick the files you do not need, and click "OK" to confirm the operation. Or you can click "Clean up system files" to free up more space.


Way 2. Storage Sense

To clean up your slow computer, you can also use Storage sense which is an automatic PC cleaner for removing temporary files. Here are the detailed steps:

Step 2. On the Windows Settings interface, click on "System".

Step 3. Select "Storage" on the left side and toggle the "Storage Sense" button to "On". It will free up your disk space automatically when your PC is low on space. Or you can select "Configure Storage Sense or run it now" and click "Clean now" to remove the temporary file at once.
