Assalamualaikum wr.wb
A simple virus infection is all it takes to render it useless. Or, there are times when your administrator has actually disabled Registry Editing. When you try to open the Registry Editor in one such computer, you are likely to receive the“Registry editing has been disabled by your administrator” error. Due to this error, it is impossible to remove this restriction using Registry Editor itself.

Enable Registry Editor Using Group Policy Editor

1. Click on Start. Go to Run. Users running Windows 8, Windows 7 or Vista, go to Search.
2. Type gpedit.msc and press Enter.
3. Navigate to User Configuration/ Administrative Templates / System.
4. In the work area, double click on "Prevent Access to registry editing tools".
5. In the popup window, encircle Disabled and click on OK.
6. Normally, Registry Editor will be immediately accessible. If it is not, restart your PC.

Group Policy Editor is not available on the home editions of Windows.



Enable Regedit by simply running a CMD Command

1. Open Notepad.
2. Copy the code given below and paste it.

reg add “HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System” /t Reg_dword /v DisableRegistryTools /f /d 0

1. Save the file as EnableRegistry.bat. Run this file as Administrator if you use Windows 8, Windows 7 or Windows Vista. In Windows XP, simply open the file. CMD will flash for a second and then disappear. This indicates successful execution.
2.Log Off and Log Back On.
