Hello everyone, i have reinstalled windows 10 maintaning my old files due to problems with updates. WHen i reinstalled it, the folder with the old os was created and due to this folder my hard drive was full so i decided to delete it. I used the disc cleanup software and deleted the old windows (which was around 25Gb if i remember correctly). After that, in the system files, the folder windows.old doesn't take up any space at all, but the hard drive is still full. I even deleted some files and cleaned 1 Gb, but in 2-3 days it has filled again, and it keeps filling up. My pc has become slow because of this. What can I do?
edit: it's literally losing 1-2mb of usable space every time i open it, about every 2 seconds, this is insane
