How to Create User with specific folder c:\users\name in Windows 10 for secondary microsoft family account

Question

I like to have simple none-spacey folder names like C:\Users\Alex of my windows login account and use login with a microsoft account. I get this by creating Local user account, login, then change to microsoft account type as specified here

How to rename the User folder in Windows 10?

Now I would like to do the same with family member, who is registered as Family Member (for Minecraft game connection) in microsoft.com. When I try to change to Microsoft account login on a second local user account it says

another user on this device uses this microsoft account

If I in User settings > Family add user account, then I get windows determined folder name. The folder name is not that bad nowadays, its non-spaced and first five letters it seems, but I would like to specify it my self.

How do I get around this? (I have one convoluted solution which I found and will post but I would prefer better solution)

Answer 1

Bad solution below

• Remove family member from Microsoft.com
• Add new account sign in as microsoft account (directly in Family & Other people settings > Other People)
• Remove account immediately, choose to delete users data
• Login to local account
• Change login-type to microsoft account.

I would like to get rid of the first remove family member option
