I don’t know the causes of the crash… Could be a lot of things: recently Windows updates, etc. I think config.sys is not the cause, but I remove it and msdos.sys (from the exclusion list). I know they don’t make much sense in XP :-\
Of course I did not remove pagefile.sys and the other files listed…
I just want to say: don’t do anything if your system is working 8)
Vlk is the salvation ;D
