From your OP, "... if i use disc cleanup again it acts perfect says it will remove say even up to 3TB or more of space from old update files. I run it reboot like it says and the SSD again will show it has not gained any more space".
So where is disc cleanup offering to find 3TB? Or did you mean 3GB on the SSD? Are you sure it is even looking at it?
This is what happened today and it has happened before.
Disc clean up says internet cache right after using Firefox for VOD it increased to 3GB or so so i cleared cache in firefox the browser i was using. Went back to disc cleanup without making it clean up in first place it still said that was there to regain so i let disc clean up do it. Then it vanished from disc cleanup as if it had worked.
Then i opened my computer and instead of having 3GB or so of space free it was identical remaining space on SSD. There are only two drives i know which the SSD is. Has the Windows logo on it since its the OS drive.
Tried rebooting re looked in my computer at remaining space. No change.
Then i did that further disc clean up where you see the old windows update files and such. It claimed i could regain over 4TB of space! so i was like OK tried it, it ran for about 10mins windows modules installer that always takes ages on any PC kicked in during that cleanup. I let it finish and restarted. Of coarse you can guess the OS SSD only SSD in the PC had the EXACT amount of remaining space as it did before any of this still.
I am at a loss here. Two SSD test programs say its health is perfect also it is over performing in the tests when you compare its read/write speeds to its specs. so there doesn't seem to be hard ware failure. Only thing them tests showed me was my 2nd drive a normal hard drive had trim enabled too.
Edit: Since my SSD is showing as OK and if i download a 1gb file i lose 1gb if i delete it from desktop i regain 1gb i am guessing my issue is with Windows. Or more directly updates caches and its disc clean up tool most of all not working. It seems to me this may well be a very annoying Windows 10 bug that has somehow kicked in and i might have to reinstall.
PS i have anti virus did a full scan. Then did two scans from manual anti virus/ malware tools. Nothing bad was found.
