It sucks. There are always troubles and problems with it. For exapmle sometimes it can't see the video-driver, the audio-driver, and so on. Installing Windows is hateful. If you don't know too much about the computers you always need help. It annoys you and the person who'll give you help.Anyway, i needed this, because my PC was a mess, and I'll have some work on it, so I had to do the reinstall. After all, it was worth it, i hope it'll be faster, stronger, harder. I still have some work with it (copy my saved files, make a new partition) but it'll be finished soon.
So, if you can, avoid installing Windows. It's not fun at all.
