How to enable/disable Registry Editor

This hack will allow you to enable or disable the registry editor. If registry editing is disabled by malware or by administrator, you can use this tweak to regain registry access. Also you can disable registry editing if you don't want to allow anyone to perform any changes to the registry, especially in a public computer like in a cybercafe.
There are three possible ways to do this:

1. First of all open notepad or a text editor of your choice. Then copy the following text into it and save it as "Enable Regedit.reg". Double-click the file and select yes when prompted and Registry Editor will be enabled. You can also right-click the file and select "Merge".
   
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools"=dword:00000000

   
   To disable the registry editor just change the dword value to 1. Or you can create another file and name it as "Disable Regedit.reg". Here is the code:
   
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools"=dword:00000001

   
2. This method is possible only if Group Policy Editor is enabled. Click Start Menu and select Run... Type "gpedit.msc" (without the quotes) in the Run dialog box and press Enter. When the Group Policy Editor opens, Go to User Configuration --> Administrative Templates --> System. Now in the right pane, double-click "Prevent Access to Registry Editing Tools". In the dialog box that opens,
   • Select Disable - To Enable Registry Editor.
   • Select Enable - To Disable Registry Editor.
   Choose OK, close the Group Policy Editor and Restart the computer.
   
   
3. This method is the easiest, click Start Menu, select Run. In the Run dialog box, type the following code and press enter.
   • To enable Registry Editor:
     REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f
   • To disable Registry Editor:
     REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 1 /f
   You can also save these codes into a text file and rename it as *.bat (replace * with your desired name). On double-clicking the batch file the required action will be performed. These codes will also work in the command prompt.
   

These tweaks are for experienced users, modifying registry can make the system unstable. So do this at your own risk.
