Under certain circumstances, the Desktop.ini file may cause the User Profile folder name on the User Store to change from the User Name to "My Documents". If we delete the "desktop.ini" file in the "My Documents" folder, it changes the folder name back to the correct user name.
Go to:Group Policy -> User Configuration -> Preferences -> Windows Settings -> Ini Files
Create a new Ini File entry, with the following settings:
Action: Delete
File Path: %userprofile%\Documents\desktop.ini
Section Name: .ShellClassInfo
Property Name: LocalizedResourceName
Ensure that you enable Run in logged-on user's context under the Common tab.
This will remove the offending line from the user's desktop.ini folder, fixing the folder display name behavior, and leaving everything else intact, including any other user-set folder view customizations, etc.
