Let’s face it the built in Windows task manager is pretty rubbish – I’ve been using ProcessExplorer on my dev VM’s for some time mainly because of the fact that it shows which DLLs that processes have opened or loaded.
Also in its latest update it better monitors Chrome and multi-process apps – see Lifehacker’s article on it here:
I therefore decided that I would replace the built-in Windows task manager on my laptop with ProcessExplorer – this is available from a menu option within the app but it didn’t work for me.
Clicking the menu option did nothing – as I understand it there should be a tick next to this option if the operation has worked correctly. When trying to launch task manager i got the following error message – “Windows cannot find C:Windowssystem32taskmgr.exe”
After a bit of research I found the registry key which contains the path to task manager –
“HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionImage File Execution Optionstaskmgr.exeDebugger”
It seems that ProcessExplorer sets this value to "AL?" which is no good really and therefore windows cannot find taskmgr.exe.
To fix the problem simply copy the ProcessExplorer exe (procexp64.exe if your a 64 bit user) to somewhere such as Program Files and update the registry value accordingly.
You should now be able to launch ProcessExplorer using CTRL+ALT+DEL or from the taskbar.
Hope this helps
