I'm not convinced this is actual unsusable space.
I'd try filling up that 200GB partition, with a reboot or two in the process.

It is showing ~80GB free space. I'd find 90-100GB of random files, and copy that to this partition. See what happens.
i checked another pc and it too has about 30 gb of unknown space maybe it's supposed to be like that

Right.
My pic above shows 12.6GB of that, and on the second run...none.

It is just data that WinDirStat can't categorize, hence <Unknown>. Space Windows uses in the background, as space is available.
i tried creating a 100gb test file in C drive and it says it doesnt have enough space but a 80gb file works

Apparently TreeSize can delete Unknown files but i can't get it to see it

I think i will just leave it be for now. If it becomes a problem later i will deal with it. Most likely it's just some windows stuff that's intended. Thanks for the help.
