I finally got around to updating my netbook with Windows 7 Ultimate this last week and all went well on it (for the most part). As most people have discovered, the vSphere client does not work native in Windows 7 and is stated here on VMware’s support site. I didn’t want to run it in Windows XP mode, but also didn’t want to wait until VMware fixes the issue either. So I did a trusty google search and found this article for the vSphere Client, and this article for the Host Update Utility. Both worked as advertised and haven’t encountered any problems since then.
