A Windows 7 feature that is disabled by default is “Concurrent remote desktop sessions”. Basically, a concurrent remote desktop session allows several user to connect to a system trough the remote desktop feature, so multiple user can access and control your system.
By default Windows 7 has a session limit for remote desktop connections (simply because it’s more secure) that only allows one simultaneous connection.
If you want enable multiple sessions, for whatever reason, then you got to patch the file “termsrv.dll”.
Deepxw, who is also the creator of the Universal Theme Patcher that allows you to install unsigned Windows 7 themes has developed an awesome tool that allows you to enable concurrent remote desktop sessions with just one click.
Make a backup of Termsrv.dll!
Make sure to create a backup of termsrv.dll before you apply this patch. It will automatically create a backup file before you apply it, but better safe than sorry! You can find the termsrv.dll here: C:/Windows/System32/termsrv.dll – copy it to a location that you regularly backup.
Original Termsrv.dll x64
If you need the original x64 termsrv.dll because you forgot to make a backup, you can download it here:

question: does this also enable the remote desktop host for win7HP ?
If HP stands for Home Premium, then no.
Actually there are only two editions that can be used as a remote desktop host and that is Professional and Ultimate
You can estasblish a remote desktop connection, but someone else can’t connect on your PC.
It’s looks extemly nice, but i’m wondering how secure this is to use a file found on the internet from a page unknown by me. Is this file located on some of the more known pages where you can download file?
Got a question.. I mess up with the concurrent login and would to disable it and restore it back without having to re-install the entire Windows 7.
Other than to copy back the original termsrv.dll, is there anything else I need to do to revert back to its original state?
