How to find out if the Microsoft products in the organization were activated with one key?

Question

System administration

How can I find out that on the computers of the organization Windows was activated with the same key?
I will describe the situation. There is a key from Win 10 under the EAS subscription. The organization has 70 computers, 40 of them are activated using this key (I did it myself). The rest of the computers have Win10, but it's not clear what key they are activated with (the previous admin quit). I thought I would go to all the computers with the Produkey program, then I would compare the keys and find on which computers the subscription key is used and on which the left keys. But Producey shows some kind of game. That is, even on those 40 computers where I personally entered the subscription key, Produkey shows different keys. I also tried ShowKeyPlus - the same thing.
Please help me with this issue.

Quite rightly advised - you need to start ... with accounting. That is, you go to the girls, you say that you need information about purchasing M$ products. And you look - what versions, how many, for which legal entity (this is very important!) Was purchased.
Of course, the stickers must be pasted. But they are looked at only if the check is that the check mark is behind :) With a more or less normal check, they start with accounting and the same question - but show me the documents confirming the purchase of N licenses for M products?
At the same time, I highly recommend the 10-Strike program (no, this is not an advertisement, I'm just a user). I recommend even buying - it is Russian, the price is reasonable. This program will collect all the data - both for M$ products and for others. This is called "software inventory".
