I appreciate all of the privacy and ethics-associated reasons why it is preferable to start a Windows 11 installation with a local account, but if I could just add one more...
When you use a Microsoft account to do so, the operating system still requires a fucking username for the name of your user directory (because a local account must be created regardless, yes,) and all it has to go on is the email address you used to set up your Microsoft account.
A few years ago when I first installed Windows 11 on my home PC, the email address still associated with my primary account was ihadtopee@gmail.com.
So, what do you think my user account folder was named? You'd probably assume it'd be ihadtopee, right?
No. Through whatever process they set up to decide upon this, Windows 11 came up with ihadt.
Perhaps it makes me a superficial person, but that shit bugs me far more than anything else about the whole thing.
Datestamp horror.
