How do you open the Task Manager in Remote Desktop? If you haven't figured it out already it's as simple as doing a Cntr + Alt + END.
Here are some other great tips below:
Alt + Page Up – Switch between programs (Alt + Tab is the local command)
Ctrl + Alt + End – Display the Task Manager (Ctrl + Shift + Esc is the local command)
Alt + Home – Brings up the Start menu on the remote computer
Ctrl + Alt + (+) Plus/ (-) Minus – Minus takes a snapshot of the active window and plus takes a snapshot of the entire remote desktop window.
