There is still a way to use Windows 11 without a Microsoft Account
Microsoft has been gradually shutting down the various ways people found to install and use Windows 11 without a Microsoft Account. The company has made it all but impossible to install the operating system without creating or signing into an account.
With the most recent preview build of Windows 11, Microsoft nixed a script that could be used to sidestep the requirement -- although it can still be manually applied via the registry. But there is still an easy way to avoid having to use a Microsoft Account.
