Title says it all, my desktop PC with W8.1 is running so perfectly, so smooth, I don't want to risk anything by doing the upgrade to W10. Moreover, I fear driver problems and general fuckups if I just update it, with no clean install.
And I do not want to lose my data for now, for a clean install (format C) would mean I'd have to download so many things again. I don't have the time and/or nerves for this right now.
On the other hand, after such a long waiting time I could finally download W10. Apparently the OS is quite nice overall...
What should I do....
