Locating Windows Key on SSD.

[JLCitadel]

Quick details:

 

Bought OEM version of Windows 7.

Threw out CD case. (I know, I know.)

Upgraded to Windows 10 for free, no issues.

X years go by

I build a new PC - accidentally use old PSU cables for old hard drive / ssd, doesn't work so i set aside for later.

I download and install windows 10 on my new M.2 drive using the free version.

I finally got around to installing my old drives with proper cables.

I'm still using my M.2 drive as the boot with the free version.

I am using a new motherboard.

 

How can I find my windows key on my old drive and see if it will work?

 

I know it's supposed to be in the sys32/config folder, but not sure how to make the files readable? Do I somehow use regedit to access the older database?

 

Should I just try to boot into it and see what the key is? [Old drives weren't listed in boot devices in BIOS so gotta figure out why]

Try this:

 It can extract it from a mounted Windows folder without booting it.

Was able to figure it out with a clear head quite quickly and easily. Just downloaded to desktop / extracted / Ran as administrator

 

Clicked on the square in the top left that looked like a cmd icon of sorts, selected the file directory of the other windows version, and ran it.

 

Got the product ID and key no problem.
