Disk space showing 100% on Notebook

[Swoppit]

My notebook is hardly ever used and I have not downloaded or saved anything other than virus software and a few word files but it is painfully slow and the task manager is showing disk space 100% full however when checking the programs nothing appears to be using any space?

This Notebook has always been very slow even from new!  Can anybody tell me what I can do to solve this other than bin this piece of crap?

You didn't say how long you have had this PC, but if it is more than six months, since you are running Win10, even though YOU have not downloaded or saved anything of significant size, the same can NOT be said of Windows.  It has been doing Updates ever since you first started it, and every time it did that, it saved off a copy of everything that got updated or replaced. Over time, all that stuff builds up -- into GB of used storage!

However, here are some things you can do to recover some of the "disk" space:

Also, the community Win10 Forums has the following suggestions:
