I found a way to get into the registry editor if its been disabled, heres how you do it:
1. Disable as much as you can from your startup. Remove programs from your startup folder and such, so as not to lag down the bootup process.
2.Create a new shortcut on your desktop, point it to “C:\Windows\regedit.exe”
3.Log off, then log back on
4.As soon as you see your desktop, double click on the shortcut. The system does not check for policies until a few seconds after it booted up. If you click on the icon fast enough, it should let you get in.
After that, do all you need. After you close it though, it will not open unless you redo step 3 and 4.
I found one vbs script to enable the registry editing. and below is the link.
The way to get into registry editing is simple. Open your start menu click Run and paste in the folowing command: REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f Submited By HaXxOr.
