Important! Because an activated User Account Control (UAC) on your system some functions of XAMPP are possibly restricted. With UAC please avoid to intall XAMPP to C:\Program Files (missing write permissions). Or deactivate UAC with msconfig after this setup.
I was searching for any farther information, but nothing found. Does anybody know what exact problems might I have if I would install XAMPP on Program Files with enabled UAC (especially on Windows 8/8.1)?
