Changing password in RDS-in-RDS session

It was already a common knowledge for me that for starting password changing dialog in a remote session CTRL+ALT+End shortcut should be used instead of CTRL+ALT+DEL. Simply because the latter always opens the dialog on the outer computer.

There is a Registry change that forces almost all shortcuts to be handled by a remote session. In the following key set the value for "TransparentKeyPassthrough" to "Remote". Unfortunately it does not work for CTRL+ALT+DEL.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Keyboard

A solution is to start the on-screen keyboard (OSK.EXE), press CTRL+ALT on the physical keyboard, and then press DEL on the on-screen keyboard. This places the shortcut exactly where it should be placed -- in a session that hosts the instance of the on-screen keyboard.

This trick works even if you are in a remote session launched from a remote session.

After sharing this information with colleagues, I was stunned to find -- LOL -- "Windows Security" item in the Start Menu. As they say: these things happen.
