MSDN and Technet had all of the versions of Windows 7 Retail since August 6th, 2009. Your curiosity could be construed as a piracy accusation, which isn't really nice, considering that the entire Internet knew that people could get Windows 7 starting on
August 6th if they were subscribers to various Microsoft services. :)
i have no problem with aero preview after waking the system from being asleep if the system has been asleep for a "short" time. If on the other hand the system has been asleep overnight the previews are "forgotten" by win 7. there must be some sort of
time out value that causes windows to forget the previews. does anyone know how to up the timeout on this value? what is the magic registry field?
ok. this appears to be part of the problem WRT preview. if your computer hybernates instead of sleeping then the thumbnails go away. even if you tell your computer to sleep there are some settings under the power options that tell the computer to hybernate
after n minutes of sleeping. the number of minutes to wait in sleep mode before hybernating can be altered via the control panel power options. navigate to
Advanced Settings -> Sleep -> Hybernate after then set the time to never or whatever you want it to be
