Disk 100%

Disk started showing 100 percent in task manager today when laptop was laggy and driving me nuts.

Have tried literally every fix I can find and nothing worked.

Welcome to the path. In task manager if you sort the disk uses what is doing it?

I honestly can't see anything that looks like it's taking up huge space. The first three things McAfee core service says 0.2MB after that it says system 0.1 and everything else says 0

I should also add that I have pretty much zero tech knowledge and don't really understand jargon and processes etc

Can you post a screen shot from taskmanger with the disk sorted too high low
