Task Manager Control:

https://old.reddit.com/r/techsupport/comments/gqb915/i_wrote_task_manager_and_i_just_remembered/- Cntrl + Alt + Esc = restart hung or frozen task manager

  • If Task Manager ever becomes internally corrupted, kill/close it. Restart it while holding down CTRL, ALT, and SHIFT, and Task Manager will reset ALL internal settings to factory fresh
  • CTRL-SHIFT-ESC will launch Taskmgr without any help from the Shell, so if the Shell/Explorer is dead use this key combo to bring up TM and then reset/restart the shell. Even if your tray is missing and gone, this combo should start it.
  • If the shell can\'t start something or is hung, try Task Manager. It has a mode where it will load without ANY references to the shell32.dll and allow you to start programs like CMD.EXE without the start menu.
  • You can find the binary for any executing process in the process table by right-clicking and pick Show File Location. You can also search it online, but I don\'t know if they have useful info for much.
  • There should be nothing that TaskMgr can\'t kill - it will even escalate privilege and (if you have it) enable debug privilege to attach to and kill apps that way if needed. If TM can\'t kill it, you\'ve got a kernel problem.
