Quick tip today, remote sessions via tools such as logmein, or gotoassist are become quite common now for remotely supporting PCs.

However a common problem is how do you send a Ctrl-Alt-Delete to a remote PC as pressing this combination only works on the local PC.

Well try one of the following:

Ctrl-Alt-Ins

Ctrl-Alt-End

Ctrl-Alt-Home

These are the commonly used alternatives to get around the problem.   For instance LogMeIn uses Ctrl-Alt-Ins.
