I'm generally not an early adopter of Windows service packs on the laptop I use for work, but I'd been running Windows 7 SP1 on my home PC for a while without issues and decided it was time to take the plunge on my eGroup laptop. The service pack installation went flawlessly and everything seemed to run great after the reboot.

It was a week or two later that I discovered a problem with VMware Workstation being unable to obtain the RAM needed to run a W2K3 VM that had always run perfectly before.  In researching the issue I learned that W7 SP1 changes the way the OS allocates memory, causing VMware Workstation to fail. The issue is documented in the VMware KB article found <a href="http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&amp;externalId=1036185">here</a>.

I didn't like any of the fixes described in the article at the time, but my problem was resolved when VMware released Workstation 7.1.4 a few weeks later.  Installing the new version resolved the issue for me and I was back in business.  The KB has since been updated with this information.
