In mta windows 7, my serial number has changed, but not in Windows 10.
I have two Windows, from each Windows, I have a different serial, this new serial only changed in Windows 7. Maybe this will change after the update or I don't know.
I don't know why it changed in Windows 10, now the new serial may replace my old serial. To solve the problem, we restored Windows 7 and looked at the serial in mta host game. We saw that the new serial changed to the old serial, but not. When I connect to the Internet, I am disconnected from the host game and it tells me to update mta. When I connect to the server, it gives an error. You got kicked from the server, it's the same new serial again.
New serial:

My old serial:
