Win11 How to RDP on computer where username contains non-ascii chars?

Question

After updating my system from Windows10 to Windows11 I am unable to login via remote desktop into another computer where the login contains a non ascii character. It always displays that provided credentials do not work despite providing the correct ones. That another computer has 2 accounts on it, where one of those contains non ascii character and the other one does not. I am only not able to login on the one with non ascii character. The other one works seamlessly.

Couple years ago on that other computer I changes the username to not contain non ascii character, but unfortunately Windows lies about changing username because it only changes the displayed name. Couple weeks ago I tried to change all the registry keys which contain the username with non ascii char (while being logged on the other account), but after restart Windows always changes them back.

Two questions:

1. What shell I do to be able to use RDP on Windows 11 and be able to login to a computer with non ascii char in a username?
2. Or what shell I do to force Windows10 (the other computer) to change the username to not contain the non-asci char?

Answer 1

Hello,    

If you're using a local account, you can enter "compmgmt.msc" to access the Computer Management console and change your username there. For domain users, the username must be changed within the domain settings.

Hello,

This question is quite old, but I had the same problem and still couldn't find a satisfactory answer anywhere.

After endless trial and error, I finally came across a solution:

You just have to enter the USERNAME in all capital letters.

At least that worked for my problem with the remote desktop connection... :-)
