Hello Costatapfumaney, and welcome to Seven Forums.
This is a long shot, but you might see if this may be able to help. Before you do this, backup anything else you do not want to lose to be safe.
First, enable the built-in administator account
and log on to it. See if the user folder is there now, and if you may be able to just rename it back to it's original folder name. Restart the computer, and see if you may be able to log on to the renamed account again.
If not, then log back on to the built-in Administrator account and pick up at step 6 in the tutorial below.
User Profile Folder - Change User Account Folder Name
When you get to step 12, look to see if there is a long number S-1-5-....
key that has the user account's original user folder name before you renamed it included in the Data
column of ProfileImagePath
in the right pane. If found, change the user folder name part of the path to what you renamed it to at step 14. When finished, restart the computer to see if may be able to logon to the renamed account again.
Hope this helps,
