How do I send a Ctrl+Alt+Delete when connected from the Screen Sharing app to a Windows computer?

Solution 1:

After some searching, I found the answer. On the mac keyboard, you have to press

Ctrl + Option (Alt) + Command + Delete

ctrl+option (alt)+command ⌘+delete ⌦

Solution 2:

One handy tool when remoting to Windows is to use the On Screen Keyboard. Just hit the Windows Key icon, and type 'OSK' and hit Enter. This will let you invoke any key combinations you need.
