Changing password in remote desktop on Window

Developing a large scale project often require many machines in the system and remote desktop into them to work on setting and checking on the data is inevitable. And with the high security standard nowadays, often time we are required to change the password every 3 weeks.

So I remoted into a machine today and it told me that my password would expire in 5 days and I tried to change the password. It told me to press "Ctrl + Alt + Del" to do it, yet when I pressed it, it triggered the action on my local machine instead of the remote machine. It was after some investigation and asking around  that I learned to trigger the same action of "Ctrl + Alt + Del" on a remote machine I need to press ""Ctrl + Alt + End" instead.

Do you know about that before? Any other tricks you think it is useful for remote desktop operation?
