Several times over the past couple months I've had a problem with Windows/system/config/system disappearing,which causes me to have to re-intall windows,etc...I use Acronis True Image,so it takes less than an hour,but its still a pain....everythings working fine,shut the PC down and when I turn it back on SYSTEM is missing or corrupt again.My question is is there away to back the registry up to a seperate drive and if so how can that file be run from the windows repair console???? will take any help I can get,this is getting really annoying...
