Hey there TLG fans,
I just updated the TechNet Library and Microsoft Download Center versions of the Test Lab Guide: Base Configuration for the following:
Note that published modular TLGs may not be updated to allow both Windows 7 Professional and Windows 7 Ultimate as the operating system for CLIENT1. They will be updated in their next refresh. In the mean time, CLIENT1 can run either Windows 7 Professional and Windows 7 Ultimate.
Also note that if you are using the evaluation version of Windows 7 Professional for a Hyper-V virtual machine, you will need to download the 64-bit (x64) version.
