I ran across an error when launching task manager in Windows 7 which was “c:\windows\system32\taskmgr.exe The parameter is incorrect”. You can see a screen shot of the error below . When I first received this error I was stumped as I had never had an issue with task manager in my life. I then started thinking back to what I had done in the past few days and remembered what I had done. I had enabled process explorer from sysinternals to replace task manager. This is no big deal, but if you move the process explorer executable to a different location it is a problem. I had been doing some house cleaning and moved the exe to another location. To fix the problem all I had to do is launch process explorer again and under options select restore task manager. When I had completed this process task manager started up without a problem. Hopefully this post comes in handy to somebody else running into the same problem.
