LEGACY keys cant be deleted ..(easily) . See this following :

1) Start -> Run: regedt32 -> OK (logged on as administrator)

2) Now to HKLM sub-window and take the key which you want deleted. Highlight it.

3) In the Regedt32 window menu select Security -> Permissions.

4) Change the access permissions for Everyone and/or Administrators to Full Control. Apply the settings.

5) Repeat 1-4 for all keys you need deleted.

6)Close Regedt32 and open Regedit. Delete the keys you don't want anymore.


Note : Administrator does not have full control over the registry. There are certain keys that only SYSTEM can touch unless an admin changes the permissions.

Download PsExec from http://www.sysinternals.com/utilities/psexec.html


First Create a folder in your C: Program Files and name it PsExec. no take the psexec file and put it in that folder .Create a batch file by opening Notepad and copying and pasting the following line into it :

Start "" "c:\Program Files\PsExec\psexec" -i -d -s c:\windows\regedit.exe

Save the file as PsExec Regedit.bat .

When you click on the .bat file you've created it will open regedit in such a way that you should be able to delete the legacy keys
