Interestingly, Microsoft doesn’t let you set up a copy of Windows 11 without an active internet connection. Unless, of course, you use a workaround to install it without connecting to a network. This also means you compulsorily need a Microsoft account to sign in as part of the process. Apart from privacy concerns, another drawback of setting up Windows 11 using a Microsoft account is that Windows automatically names the User folder with the first five letters of your email ID.
