Can I run Regedit on a drive that the computer didn't boot from?

I'll explain why. I regularly do a hard disk to disk copy backup of my
hard drive. Recently, I purchased the 2005 versions of some EA Sports
videogames and unistalled my previous 2003 versions. The teenagers who
play them (I'm a counselor of teenagers) liked the 2003 versions
better. But to reinstall them, I need the Key from the back of the CD
cases which I had thrown out. However, since I have a backup of the
hard disk, the registry entrees are there and I just need to enter
them in the registry of the current C: drive and the games will run.
But it is a pain to disconnect the current C; drive, connect the
backup hard disk copy the registry entrees to a text file, reconnect
the current hard disk etc. I'd rather just put the backed up hard disk
on the secondary controller and check the registry on it. How can I
run regedit on a disk that is not the currently bootable disk?

You surely only have to do it once if you save the Registry entries,
preferably by exporting them to a .reg file that you can use.

If you really want to read a non-current Registy:

Regdat - Browse old Win95/Win98/Me Registry Files.

RegExport is a basic version of Regdat designed for users who want to
occasionally export information from old Win9x/WinMe registry files.
Registration rate is US $8.
