-I did try the /l /r switches, with full path, along with of course being in the same dir as the .dat's (/windows), and of course did the attrib -r -s -h *.dat to make sure they were available... -it's the same w/all versions of regedit.exe, 98se/ME/updated/"fixed"... -combined size of user.dat + system.dat is 7mb... (old-install test system, lotsa installs/uninstalls... but I do clean/optimize it regularly) -and nope, no batch file to back it up, just standard/auto... -it's no big deal, was just curious... I also keep many generational copies of reg, prob won't ever need it, but was thinking of all poss. emergencies, it'd be nice to be able to edit the reg from real-mode if windows won't boot... but I also keep "safe" copies of windows on C, so prob won't ever need this, but just in case...
