How to understand from which disk Windows was installed?

Question

Windows

Hello.
I have two computers.
Both have win-7 installed.
Also it was put from two different disks.
Of course, I forgot to stick the stickers from the disks on the system unit.
Now I want to rearrange the system on one of the machines.
How to understand which machine has which disk?
I correctly understand that the license key is not visible after installation?
Maybe it is at least with the numbers in this window:

does it have a one-to-one correspondence?
(well, not specifically in this one, but in the same one, but from Win-7 :))
Then it would be possible to remember the numbers, rearrange ... and if it didn’t match, rearrange from another disk :)
What to do then? :))

Answer 1

AIDA64 shows the original keys in clear text. section "Software / licenses"
at least all the main products of MS - Windows, office, studio, school, etc. useful to check - only Windows, school developer and community studio, and office 2013 is boxed, with a key, but not shown .. strange. maybe something has changed over the years ..
nevertheless - Windows cheerfully shows to this day
ps Windows disk matters, only in the case of different editions. but the key is never written on the disk*. the key is only on a sticker (boxed or OEM version), or other separate media, electronic or paper, for corporate. for laptop models originally licensed for a specific edition - the key is embedded in the BIOS.
you can change the disk to a distribution with a different language, this does not affect. only the correspondence of the edition affects - home, pro, corporate, etc.
pps key can be written on disk, in a special file. but this is a technology for corporations when preparing an image for mass installation. there you can add sets of drivers, some settings. and corporate key. but such disks are usually rarely leaked from corporations.. because it is fraught with corporation gimor and negligent administrator.. and this is a very old technology. now it has been superseded by KMS activation
