What happens if a licensed version of Windows (XP, 7, 8, 10, etc.) is installed simultaneously on several PCs?

Question

System administration

I know it violates the license agreement.
I want to know:
1. After installing Windows and entering the key, you need to activate it (over the network or by phone).
What will happen if you do this every hour, week, month, year or more on the same PC or on different ones?
2. Will Windows be blocked if several PCs working under the same license are updated (in automatic mode), perhaps even simultaneously?
3. Does Microsoft (black list) block license keys that they think are on the suspicious list? (the answer is essentially obvious, but I have never encountered anything like this, so I suspect that it is not) And if "yes", does this mean that activation will not work during the next installation, and moreover, all PCs with this license at once will they be blocked or informed about the problem?
4. Is it possible to find out from Microsoft on which PCs the same license was installed and when, or is this confidential information and is issued only by special order. request?

Answer 1

1. Will be activated until the key blocks MS.
2. No.
3. Yes.
4. No, and even by special request it is hardly possible to get it.
Key blocking in the MS is automatic, but even the MS will not clearly tell you what frequency the operation is set to, because it is unlikely to get through to technical specialists, and the call center will say that one license is one computer.

Answer 2

1. Will be activated until the counter runs out. For the non-corporate version, the counter is small - either three or five, after which you need to call the call center and prove that you actually bought it, if you proved it - well, three to five again. For the corporate version, the number of installations and the number of remaining activations are shown in the license management interface.
2. No. Activated - means face.
3. Yes, and very quickly - see answer #1. Existing computers are not blocked.
4. No. Somewhere in the M$ logs, of course, there is information about who activated when from where, but they are unlikely to provide it - unless at the official request of the American Themis.
