I was browsing the hacking sites they said open notepad and type the following save it in reg format and open it:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVe rsionPoliciesWinOldApp]
"Disabled"=dword:0
[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVe rsionPoliciesSystem]
"DisableRegistryTools"=dword:0
How to undo the above
