Windows 8 new account

I recently try to create a new account on a relatively old windows 8 computer (one year, several updates).

Account creation was just fine but... impossible to connect due to the inability of the system to load the profile of the newly created user.

After some googling and hours, I finally found that the problem was the inability of the system to create, by copying from c:\Users\Default, the new profile.

I found which files were involved with the windows events observer:

Once the rights fixed, I was able to use the new account.
