Running cmd as admin crashes Explorer ntdll.dll error

I'm tweaking my new PC and I need to run cmd as admin for certain purposes. However, when I try to run it as admin (by right-clicking a desktop link and choosing "Run as admin"), it crashes Explorer.exe and no prompt appears.

Here is the Event Viewer entry:

explorer.exe
6.1.7601.17567
4d672ee4
ntdll.dll
6.1.7601.17725
4ec4aa8e
c0000005

C:\Windows\explorer.exe
C:\Windows\SYSTEM32\ntdll.dll
255f9932-4f42-11e1-a124-50e549d2ec0f

This happens even after a clean boot.

As a matter of fact, Explorer.exe crashes VERY often and I can't pinpoint exactly why. (Happens while just viewing files and whatnot.) But it always mentions ntdll.dll.

How are you tweaking your system??Are you using 3rd party themes and such.Usually incompatible themes and their underlying files causes explorer.exe to crash.Try to remove the theme and then check if explorer is crashing.

I'm changing miscellaneous system preferences, making cosmetic changes, turning off unwanted Windows features, etc. I'm not using a third-party theme.

You can run sfc /scannow in cmd as admnistrator to restore default windows file.

I can't run cmd as admin. That's the reason I created this thread. Nevermind. I figured out a way to do this. Running scan now.

Here is an excellent link with the same problem as yours Windows 7 explorer.exe keeps crashing - ntdll.dll fault - Microsoft Answers.

Check it out and let us know.

I'm digging through various threads now. I've enabled dmp files for explorer.exe, do you want me to share them when it happens again?

I believe I've solved it. I downloaded ShellExView and disabled the Spybot Search & Destroy context menu. My original problem has stopped, and so far Explorer hasn't crashed. Anyone else with Spybot who is having this problem might give that a try.

Thanks everyone for your help and suggestions.

You are correct azhe. I had the problem , almost every time I right clicked on a file name in Windows Explorer and it crashed.

About a month back I came across ShellExView , like yourself, and experimented disabling some of the context menu settings for certain non-Microsoft programs. The Spybot context menu option was the culprit so now permanently removed this option from my context menu.

Not one crash since. Just tested enabling it and immediately Windows Explorer crashed when I used the right click option, so this definitely is the problem.
