Is a Registry Tool Database file completely Cross Platform Compatible?
Absolutely! You can even take a Registry Tool Database file created in Windows Vista and send the keys and values into Windows 95. The only real limitations are that you can not create a new root key of HKLM in Windows NT/2000/XP/2003/Vista and Windows 95/98/ME does not contain Registry Security information, so you can not send Security information into Windows 9x/ME.
