How to Clear Temp Files in Windows 10
1. Open Disk Cleanup.
You can search “disk cleanup” in the search bar in the taskbar and click the first result, which is the app.
This is the easiest and least involved method for cleaning up temporary files on your Windows 10 computer.
You can also press the Windows key+S to open the search function if you can’t find it in the taskbar.
2. Click to check the boxes next to "Temporary Internet Files" and "Temporary Files."
You’ll see how much space they will free up along the right side of the columns.
Suggested boxes to delete are checked by default; you can leave these checked and delete these files or you can click to uncheck the box and not delete these files.
3. Click Delete Files.
Click “OK” to confirm the action when a box pops up.
When you continue, that box will disappear and you’ll see a progress bar of the deletion, which will disappear when it’s done.
