Not overly exciting, but packed with good information for beginning the assault on Windows7. I have been a long time windows user, my main machine is a macbook, and I have several linux boxes kicking around also. This free PDF explains a lot of the Windows7 features, and im going to shoot it off to my Parents (who are using Vista) to give them a quick overview.

JvmMs = 0x0

JvmMx = 0x0

JvmSs = 0x0
