Regedit disabled by administrator

Hi,

My 3 team members are not able to open REGEDIT from last 10 days. it says disabled by the administrator. I have checked group policies and no such policy applied on these users.

These three members are from transitions/testing team and they are not able to test tools just because of this.

If not set by policy, then it is usually a sign of some type of malware. Try downloading and running this vbs script. It toggles the state of regedit. If it is disabled, it will be enabled. Enabling requires a restart, so reboot to test.

If that does not work, then try this sequence:

Click Start -> Run. Type this command in Run box and press Ok.  (You can copy and paste)

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

Then a prompt will come up with this question: Value DisableRegistryTools exists, overwrite (Y/N)? Type yes and hit Enter.

After u did that also type this command in the run box and hit enter.

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

Then it will also come up with the question: Value DisableRegistryTools exists, overwrite (Y/N)? Type yes and hit Enter.
This article ahs several different methods of fixing the issue.  I typically use Method 4.

run regedit in safe mode and make the alter as above. The problem came due to virus affected check with sdat .exe. once virus is remove then do the regedit work.

If u do regedit before virus remvel no effect with be there.

i did all the methods but no luck.
I believe its due to some virus, we are using Symantec EndPoint Protection but that does'nt work for this virus.
Can anyone provide me any other free tools/exe thru which i can scan and remove this virus/malware.
Try this:

http://www.dougknox.com/xp/utils/xp_emergencyutil.zip

Look here for instructions:
http://www.dougknox.com/xp/utils/xp_emerutils.htm

Basically, it creates new versions of regedit, taskmanager, and msconfig. Try using the new regedit as instructed. If it works and you get in there, chances are that the following key is remapping all that great stuff to svchost so it looks like nothing is happening. Look here in the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

Within that key, I bet you find a ton of entries, each of them remapping a "good" program to a bad. This stops the program you want from executing. As a start, scroll down the list and look for regedit. If you find it, highlight it and delete. You can actually delete every entry in that key.

Rename c:\windows\regedit.exe to c:\windows\blah.com

Does it work?

If so, look at the following....

start>run>cmd

Paste the lower commands...

Do they return results? Most likely the keys can be deleted.....

second set deletes them if present.....
reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\regedit.exe"
reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\regedit.exe"

reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\regedit.exe" /f
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\regedit.exe /f

Open in new window

Likely due to malware/viruses present in the system, so when you fix the symptom while the nasties are still there it won't work as it will be disabled almost immediately.
Use the already suggested tools to fix the symptom and then scan the system to remove the culprit.

As suggested, scanners you can use to scan the system:

MalwareBytes:

HitmanPro:

TDSSKiller:
