Startup tab

The Startup tab lists the programs that might be automatically started when a user logs on and allows to enable or disable their execution.
The corresponding values are found in the registry below the keys HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run.
The information about the enabled/disabled status is found under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\Run. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\Run

Starting Task Manager

The task manager can be started with the keyboard shortcut ctrl+shift+esc.
Alternatively, it can also be started via the Power User Menu by pressing windows+x then t.
On the command line (cmd.exe, PowerShell), the Task Manager can be started by simply entering the name of the executable (taskmgr): 
P:\ath\to\dir> taskmgr

Freezing the process list

Holding down ctrl freezes the process list which allows to select items from it more easily without jumping around.

Alternatives

A better alternative for the task manager is probably the Sysinternals Process Explorer.
The process tree can be displayed with tlist.exe /t (Debugging tools for Windows).
Sysinternal's process explorer
