frantheman: how did you measure your registry size?
as shawn suggested, i exported my complete registry as a reg file, and mine seems a bit bloated at 195 megs.
(i've defaultly associated my reg files with notepad, so a quick careless double-click won't merge.) as far as i know
, the windows 7 registry is actually contained within several files stored at a few locations. adding these all up, i get maybe 70 megs, but i suppose these are compressed somehow compared to the text-based .reg export, and are hence stored more efficiently.
