Operating system update and backup

[Freccia]

Hi, I should update my operating system from Windows 8.1 (64bit) to Windows 10 (64bit).

I would not want to lose the settings of my GSX and Level 2 (P3Dv4.5): which folders/files should I backup?

Thank you.

If depends which kind of update you do. If you do an "update in place", the option to keep you personal files and settings, you won't lose anything. If, instead, you do a full reinstall with a clean installation, then you should backup this folder:

%APPDATA%\Virtuali

Which stores all your GSX custom settings.
