This tutorial will show you how to delete temporary files on your drives in Windows 11.
Windows creates temporary files while installing apps, loading web pages, or running updates. Left unchecked, they can use and hold up storage space.
Temporary files serve a purpose in the moment—they help Windows and apps run faster. But once they’ve done their job, they are supposed to be deleted. However, some can linger: system cache, leftover installation files, thumbnails, even old update data. Over weeks and months, these “leftovers” build up. That’s when you start noticing lag, low-storage alerts, or even failed updates. Regularly clearing them out is one of the easiest Windows performance tips you can follow.
