How to Enable Concurrent Sessions in Windows 7 Service Pack 1 RTM

If you've been following MissingRemote for a while, you know one of our most popular series of guides is Enabling Concurrent Remote Desktop sessions. Continuing that trend we have an updated process below working with the RTM (Official Release to Manufacturing) version of Windows7 Ultimate, Professional, Home Premium and Enterprise Editions, x86 & x64 build 7601, Service Pack Build 1130. For those unaware of what it is, enabling Concurrent Sessions allows you to Remote Desktop into a system that someone else is on, under a different user account, and access the system without kicking the user off. I, for example, use the feature to have MCE running on my Television, and then I remote into my main user account to access all my files without interrupting my MCE session. Special thanks to Mikinho for compiling the package below and making this all possible.
