Why did Win 10 version 1903 create a new user

[Windows Central Question]

Got the update to 1903 (OS Build 18362.295) yesterday. Afterward, I discovered it had created a new c: user and moved all files under that account. The original is still there but has only an App Data file. The only difference in the user name is it added .000 to the end.

This has created problems with a couple of programs so far that are looking for the other account for file locations.

Is this a known issue? So far, I have just pointed the programs to the new location.

It's a known issue as far as other people seeing the same thing, but it doesn't appear to be a known issue from MS's perspective as far as confirming the problem and promising a fix. Check out this MS forum post.

I never had this after I upgraded. That's good to know.

I don't have that issue after installing 1903 although my PC got 1903 via Windows Update about a week ago. I have however seen something similiar in Windows 7 when there is a corrupt file that points to user data directories. But that was years ago lol... do these steps help?

The only other instance where a random username was created when I had a corrupt .msi installer for version of dot netframework which create a user called ASP.NET Machine Account and moved my profile settings to it (This happened on Windows 10 1803 iirc).
