Microsoft still doesn’t really care that much about piracy for some products. You can run Windows 11 Pro with 99% of the features in tact without activating it.
Yea microsoft mostly cares about the enterprise market now. They prefer people pirating windows over using other operating systems because it ensures their enterprise productivity software monopoly.
I just installed Windows 10 on a laptop using the official USB creation tool. You just gotta leave it disconnected from the internet and you can make a local account with no restrictions.
Haven't used windows 11, but there were times when 999999999 was a valid cdkey and there were times when you had to activate the OS with Microsoft servers
