Ano, lze ale neni to vhodne delat az po instalaci windows.

Takhovhle navody jsou pak risky:

1. Open Explorer.
2. Create a new folder called 'Documents and Settings' in
your desired drive.
3. Create a new profile with administrative permission and
call it "move".
4. Logoff then logon to the "move" account.
5. Copy all the folders inside 'C:\Documents and Settings\'
(except the 'LocalService', 'NetworkService', and 'move'
folders) to the new location. (The LocalService and
NetworkService folders will be re-created automatically.)
6. Open the Registry Editor and Find & Replace all
instances of "\Documents and Settings\", including:
- '\Device\HarddiskVolume1\Documents and Settings\'
- '%SystemRoot%\Documents and Settings\'
- '%SystemDrive%\Documents and Settings\'
- 'C:\Docume~1\'
7. Shutdown your computer, wait 30 seconds and turn it on.
8. Logon to the 'move' account.
9. Repeat step 6.
10. Reboot and logon to your original account.
11. Test by renaming the '\Documents and Settings\' folder
in drive C. If you can rename it then it worked!
12. If everything's OK, you can delete the 'move' account
you created before
