So, after a shortage, Windows decided that it would simply not start anymore. So I did the Refresh option it gave me because the option said that it would try to keep as much as possible (the other option was Reset which said it would do exactly that, reset everything). Now, the only thing it kept is my documents so we're off to a magnificent start already. And then there's the Windows.old folder it created that contains the previous installation. The thing is that I'm on a SSD so space is limited, and that folder is taking over 20 GB of that very space. And it won't let me delete it. So how do I do that? If the procedure is complicated or involves downloading 3 programs, then I'll just wipe. I've already pretty much lost that installation, and copying my docs isn't hard so, yeah.
