i have this- dumprep 0 -k , in my HKLM auto start.- O4 - HKLM\..\Run: [KernelFaultCheck] %systemroot%\system32\dumprep 0 -k it's the program which writes the error report for the memory dump. i dont know what the command means. can you tell me please? also in *startup and recovery* i have *write debugging information* set to (small memory dump (64kb)) should i set it to none? thanks ***EDIT*** should i be worried by how it got there in the first place? thank you.
