I know right now, there's 12.9 GB of temporary files, most of it being the old version of Windows (just got Creator's update), but other times my C drive always seems full despite the fact I don't save stuff to there, the majority of programs aren't installed there etc. It can be like I clear space and two hours later it's complaining it's full again. I don't remember Windows 8.1 using up all my space this often
Windows 10
120 GB 840 Evo SSD (C drive)
I run disk cleanup and if it opens it barely changes the situation
