Warning! This is only for advanced users, and at your own risk.
Normally when you log in to a remote computer with RDP (Remote Desktop),
the current session on that computer is automatically logged of.
I found a site named "Missing Remote" and they made a script to prevent that, thus enabling concurrent sessions.
With their script it is not only possible to log on to a remote computer, without bumping the current user, it's even possible to log in with the same account as the current user without bumping it
When can this scenario be handy?
Well, suppose someone is watching a recorded show on your HTPC, and you want to log in?
Now you can, without the person watching the show even knowing you logged in.
You can even plan a new recording without interrupting the current user.
You can do maintenance on the machine while your wife is writing an email, or your kids are doing their homework.
They won't even know you're there.
The guys at missing remote made such a good tutorial, I won't bother to write one here.
The only thing they forgot to mention, but is pretty obvious, is that you need to run the script on the remote machine you want to log in to.
Another thing I noticed is that with the RTM version you type "install multi
and when you use the build 7100 version you have to type "install -multi"
I have only tried the RTM version and that worked with "install multi", so the " - " in the 7100 version might be a typo.
If you use the " - " and when login in still bumps the current session, just run the script again but this time without " - ". This is the link for Windows 7 RTM 7600.16385 both x86 and x64 Missing Remote This is the link for Build 7100 RC both x86 and x64 Missing Remote
