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.
Error Displayed When Launching Task Manager
great info, saved me a lot of time thx …
This helped me as well. I had process explorer installed at one point and had it overriding task manager – at some point I stopped using process explorer and later decided to use it again. I must have placed it into a different location. When starting process explorer from the task bar i was getting this error. Checking Options->Replace Task Manger on and off (twice i think) resolved my problem.
Thanks a lot. I had the same problem in my case I don’t work with admin right on my machine. This is why the sysinternals process explorer shows the run admin icon on the menu.
When calling the replace taskmanger option with normal user rights you are asked to enter the admin password. After doing so the taskmanager will not start and will show the message “The parameter is incorrect!”
In this case go to the directory where the sysinternals process explorer is installed and run this program with admin rights. Now you can enable / disable the original task manager.

Great! I had to install proc explorer first. I think a prior malware deleted or moved it on my son’s computer.
Thanks @ThomasMihatsch. This was the trick I have been looking for.
