Possible to install windows 11 without microsoft account?

How I did it: Basically I had to setup WIndows 11 Pro using a Microsoft account, then created a local user account. Logging into that new account was tricky.

1 - In setup, I chose the Work/School setup rather than the personal setup
because the personal setup wouldn't recognize my Microsoft account email and password.
2 - Once setup was complete...
3 - Changed the laptop's Workgroup Name to my home Workgroup name that I had picked long ago.
I suppose you could leave the Workgroup Name as the default name, WORKGROUP, but I haven't tried that.
4 - Reboot for the Workgroup change to take effect.
5 - Create a new user:
Start / Settings / Accounts / Other Users
Other Users / Add Other User
Click Add Account.
In "How will this person sign in?" click "I don't have this person's sign-in information"
in the resultant Create Account dialog, click "Add a user without a Microsoft Account"
Enter the new user name (e.g., "Biff") and password that you choose.
6 - Make the new user an Administrator (if you wish)
Settings / Accounts / Other Users, select the user you just added (e.g., "Biff")
Click Change Account Type
Account Type: Administrator
Rebooted just for good measure.
7 - The tricky part: how to login as the new user
At the Login Screen...
Click Other User (in the screen lower-left)
Click Sign-in Options
Click the Key icon to choose a Password-based login
For email address, type the Workgroup name, backslash, the user name you created,
for example NEEDHAMIA\Biff
I suppose that's strictly-speaking a domain name rather than a workgroup name, but it works.
Type the password you chose when you created this user.
Click the arrow next to the filled-in password
Windows should now set up the new user, who doesn't use a Microsoft account.
The next time you sign in, it should offer the new user name,
so you just have to type the password and away you go.
