Hi John

Unfortunately not all of the labs are on the Drive.

However, guessing you are looking for the Windows 7 labs, many can be found on the drive in the <DRIVE>:\Windows7\Windows_Whitepapers_and_HOLs folder along with related whitepapers.

For the Azure labs, including Windows Azure, .Net Services, SQL Services & Live Services - you can check out the training kit from http://www.microsoft.com/downloads/details.aspx?FamilyID=413E88F8-5966-4A83-B309-53B7B77EDF78&displaylang=en
