Registry Editing has been disabled

Your registry editor (“regedit”) has been disabled by someone/trojan/virus? Here’s 2 solutions to it:

1. From Group Policy Editor:

Goto Run -> gpedit.msc
In the left menu, goto User Config -> Administrative Templated -> System

Now in the right pane, select “Prevent access to registry editing tools“. It will probably be not configured or enabled. If it’s enabled, disable it and if it’s not configured, first enable it, apply settings and then disable it. Most probably the settings have been applied instantly. If not, then run gpupdate in command prompt to apply the group policies.

2. From the Run menu:

Goto Start -> Run, copy and paste the following command and press OK:

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f
