A friend of Next of Windows left a comment on this post asking if there is a way to open Task Manager with Performance tab open by default. While I don’t have an answer for it, I do find an undocumented way to defaulting to Startup tab when opening Task Manager.
Here is how:
Press Win + R to open the Run dialog box, type the following command, and press Enter.
taskmgr /0 /startup
Task Manager opens up with Startup tab open by default.
The trick works on both Windows 8.1 and Windows 10 systems.
It seems that the Startup tab is the only tab that can be opened first when Task Manager is launched. I tried a few other switches but none of them brings any other tabs to open. If you know a trick, please share.
Also, the switch /0 can be substituted with other numbers like /1, /2, etc. As long as you put a switch there in middle, you should be able to open Startup folder.
Moreover, the number indicates the way how the Task Manager is launched. For example, /2 is used when the Task Manager is launched by the keyboard shortcut Ctrl + Shift + Esc, /3 is used when it is triggered by Ctrl + Alt + Del, and /4 is used when fired up from the Taskbar.
