Windows 7 64 bit Workstation 7 freezing fixed by installing vSphere

  I have a new Windows 7 64 bit SP1 system and am running Workstation 7.1.4 build-385536. I was running into the periodic freeze issue that others have reported. I had tried all the following but was still experiencing the freezes. I was about to try the microsoft hot fix that was supposed to be rolled up in SP1 when I had to install vSphere 4.0.0 to handle an admin problem on an ESX server. After that I have not experienced any freezes. I don't know why but maybe it will give someone else a direction to look in.
