WindowsXP Registry Permissions

[Mohammad Atfan Iqbal]

I hav changed the registry permissions for the hive of Hkey_Classes_Root.
And Given full permissions to accounts of System & Administrators Group. I
hav changed the permissions of both hives of classes i.e Hkey_Classes_Root &
HKey_Local_Machine\Software\Classes, Bcoz the Hkey_Classes_Root doesn't has
auditing permissions. The problem is that whenever i restart the computer
after doing this, everthing boots correctly but the screen gets locked at
the welcome screen i.e if the welcome screen is enabled using the Fast User
Switching. I wanted to know if there is a way to revert the Permissions to
default levels.

Thanx
Mohammad Atfan Iqbal

Try safe mode.

HKCR is built of HKLM\Software\Classes AND HKCU\Software\Classes with entries in CU overriding LM entries. If they are CU then CU permissions apply. If they are LM then LM permissions apply.
