[Bug report] No option or menu to revert the windows Task Manager replacement RRS feed

  • General discussion

  • I'm using windows 10. As you might already know, you can replace the windows built-in task manager with Process Explorer from menu "Options" -> "Replace Task Manager". But after the successful replacement, there is no option to revert the replacement. I expect I would see menu like "Restore Task Manager" or such.

    To restore the task manager, I had to remove the registry path "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe" in regedit.

  • When you select the option to Use Process Explorer as Task Manager Replacement, you will see a check appear near the option itself.

    If you un-check that option, it will revert back to the original setting.

  • It's different on my end, there is no checkbox at all: https://i.imgur.com/WGfdIqR.jpg

    I'm using the latest version (16.30).

  • You have the shield icon, meaning that  you are executing Process Explorer as non-admin.

    If you will run it as an admin then you will have my picture..

    And even when it is like on your picture, if you click on it after that  you will have both the check box and the shield.

    The check box is the think that will let you switch from one mode to the other..

  • Ok, this is quite strange. After seeing your post, I run the procexp64.exe (the 64 bit exe is what I used all this time) as administrator and I didn't see the shield icon, but I didn't see the checkbox too. I tried clicking the "replace task manager" menu but no checkbox showed up at all.

    Then I tried to run the 32 bit procexp.exe as administrator, then I tried clicking the "replace task manager" menu, and now I can see the checkbox, clicking the same menu again will remove the checkbox. The revert function also works. After that I tried running the procexp64.exe again as admin and non-admin, now the checkbox and revert function are working on both situations. Not sure what happened here, perhaps there is setting corruption caused by previous version of process explorer.

    This is still a bug. I downloaded and use the 64 version because that's the computer I have. And why does it matter it we are in Rund Admin mode? If that is an issue then it should not have allowed the first iteration. Be consistent. That is the design bug.

    And you should be asking why we want to Restore Task Manager. The brave ones will.

  •  And why does it matter it we are in Run Admin mode?

    If you are not running Process Explorer as Administrator, you cannot change the registry key for the Task Manager.. for that reason Process Explorer show up the shield icon near the option if you are not Admin.

    This is not a bug in my opinion, on the contrary Process Explorer show perfectly well how a program should work when it has to do with administrative options.

  • I am having trouble reinstating Windows 10 Task Manager!

    On my work PC, my account does not have admin privileges. To make changes to my system - change some settings or install software - I have to use a separate account. Thus, when I turned on the 'replace task manager' function I had to enter the username and password for the other account.

    I have to do the same to change it back, but it's not working. There is no checkbox next to 'Replace Task Manager,' and when I select the option, ProcMon runs instead.

    I've tried running the app itself using the other account, and I've tried running it with my normal account and entering the other account's credentials to change the setting. Neither works. 

    More troubling, when I renamed the two ProcMon exes to .bak, Windows was 'unable to locate taskmgr.exe.' I ran SFC /SCANNOW but it did not fix the problem.

    I need Windows Task Manager to create a dump file for a program. But I can't get to it!

    Can anyone help?

    Thanks.

  • Despite the fact that you can create a dump also using Process Explorer, you can restore manually the task manager as the default going to the registry where Process Explorer did the change and turn it back.

    Use ProcMon to log what key is that and change it back.

    As you can see Procexp create a key under taskmgr.exe with the name Debugger and the value to its path

    and when you remove it it simply delete that key.

    So, just remove that key (Debugger) and you are back to task manager..
