Rename user profile
Unfortunately, no. Once the profile folder is created, you're stuck with
it. You could create a new logon with a name you prefer and use the
EasyTransfer tool to move files, documents and settings to the new profile,
then delete the old one.
Visty tady na odzkoušení nemám, ale co zkusit vytvořit nový profil a přenést nastavení a soubory?
