How to Enable the Registry Editor When Disabled by Administrator

Registry Editor, a main registry editing tool equipped in all versions and editions of Windows operating system, can be disabled, blocked and locked to prevent the RegEdit from been ran or executed by users in order to protect important system registry. Other possibility of Registry Editor been disabled is caused by virus or worm such as W32/Brontok-C.

When Registry Editor is disabled, user unable and cannot open or run Registry Editor anymore. Any attempt to run RegEdit.exe will return the error “Registry editing has been disabled by your administrator”. Hence it’s impossible to remove the restriction on Registry Editor usage by using the Registry Editor itself. However, it’s possible to use various workaround to directly edit the registry to remove the policy that blocks Registry Editor usage.

UnHookExec.inf by Symantec to Reset Registry Values to Default Settings

In many cases, disabling of Registry Editor is caused by virus, worm or Trojan, which attempts to stop user from fixing any changes to the registry, which normally affects changes to one or more of the shell\open\command keys. For example, exefile\shell\open\command key is changed, the virus, worm or Trojan threat will run each time that system run any .exe file. As such, Symantec create a .inf script tool to reset these registry values to their default settings.

WARNING: The UnHookExec.inf will reset registry keys and values related to BAT, COM, EXE, PIF, REG and SCR extensions, beside re-enabling the Registry Editor. Hence, users who just want to re-enable the Registry Editor has to manually modify the .inf file to remove the unnecessary commands.

Download the file UnHookExec.inf and save it to your Windows desktop.

Right-click the UnHookExec.inf file and click install. Action will be taken immediately. No display, nor any notice or boxes will appear before or after running. Try to run RegEdit.exe again, restart and reboot PC if it’s still blocked.

HOw to Enable Show Hidden Files and Folders in Windows

Some viruses or Trojans is smart enough to hide themselves into a corner of the computer system, and then effectively force disable the “Show all hidden files and folders” or “Show all hidden files, folders and drives” option under “Folder Options”. When it happens, hidden files, folders and drives on the PC do not been shown or displayed even though user has attempted to apply the settings to show the hidden files. The virus implements a policy such as “Shockwave.dll” that’s forcing system to keep hidden files forever not visible or hidden.

If your anti-virus or anti-malware solution is unable to get rid of the malware, and you’re desperately need to view the hidden files, here’s the workaround to enable system to show hidden files and folders again. There are many viruses that may cause the hidden files cannot be visible error, thus the following solution may not work on some system.

• Go to Start Menu and click on Run (Windows Vista and Windows 7 uses Start Search instead).
• Type RegEdit and press Enter to run Registry Editor.
• Navigate to the following registry key:

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
  CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL

• In the right pane, verify that the CheckedValue value data is REG_DWORD type. If it’s not (such as belongs to REG_SZ), then delete the CheckedValue value data.
• If CheckedValue has been delete, create a new DWORD (32-bit) Value and name it as CheckedValue.
• Double click on CheckedValue and change its value data to 1 (virus may change it to 0 or 2).
• Within the same registry key, verify that the Type value data is of REG_SZ type, and has the value data radio. If not, set it to radio. Virus may change it to blank.
