Just to be clear, it's not one of those usual things. I got Win 7 Home Premium. CMD, Task Manager, all exe files and GPEdit works fine. Everything works fine actually - exept regedit just does not respond. I have Nod32 and my PC is virus / malware free. All I want is just access to registry editor. Things I've tried already: 1. Tried just running as administrator (ofcourse) 2. Did sfc /scannow 3. A couple of different scripts to enable / disable regedit manually including the Symantec's script. 4. Changing Group Policy Settings (gpedit.msc of preventing access to registry editing tools) 5. CMD command "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System" /t Reg_dword /v DisableRegistryTools /f /d 0 (ran as admin ofcourse) No luck yet. Anyone have any ideas? Regedit just won't react. No errors, no pop ups, nothing. Silence.
