Any chance that a techie. can help please ? MS know. base article 256419 says to backup the whole registry go Start - Run - Scanregw - Ok - Yes - Ok. It puts a new Rboo1.cab file in Windows\Sysbckup. I checked the size of those cab files and they are 1.10 MB's each on this machine. Each copy has 4 files, USER.DAT SYSTEM.DAT WIN.INI - config.settings. SYSTEM.INI - config. settings Two questions, does 1.10 MB's seem the correct size for a copy of the whole registry ? If so, will copying one of those Rb.cab files onto a floppy be quite useable so long as I refresh the copy in case of registry changes ? TIA, Regards.
