Take control of another computer

[Conrad11]

I am trying to demonstrate how you can theoretically get control of another persons computer.

Here's my demonstration setup:
-2 computers.
-Both connected on the same router (LAN).
-Control over the router (if I need to open ports etc)
-Both running Windows 7
-Have admin account credentials for both machines
-Both computers are on and logged in (or can be in logged out state if need be).

How would I go about getting control of one computer from the other without the other computer knowing? (I.e no popups or anything like that - just straight control). Is this possible without the need for extra software?

Thanks.

1) Apply the concurrent RDC patch on each machine (sourced from the missingremote website or I can upload it for you, the one i have covers all windows versions 64 and 32bit and is simple to apply)

Could you upload this for me please? Is there anyway to uninstall/reverse this without a reinstall?

All the ways we've mentioned so far, means you would need to initially setup some software on the machine you want to take control of... you'd physically need to be sat at that computer for the initial setup... but after that you are free to connect over the network or even the Internet.

It's basically for a demonstrating that it can actually be done.

I have physical access to the machine (i own both machines) so will be doing the concurrent patch thingy if it isn't possible to do with a standard install....my only question is, when I have finished, will I be able to uninstall the patch as I see that as a potential security flaw.

I take it that there is no way to do it with just the standard Windows 7 install (without installing anything). I don't care if the user can see the mouse moving etc....(if not with the standard install - what if i change a few settings?)

Lemme know - and thanks for the info so far.
