I've been running Windoze10 for a week now.. with no problems in SL using FS viewer. Although... I did not take the option to upgrade video driver as recommended during install.
I had upgraded those video drivers before.. for some reason.. (in windows7...just because it was avaiable I guess).. and had a WHOLE LOAD of problems afterwards. So I rolled them back.. and am very sceptical about trying it again. .
