WMF patch is the first patch for Microsoft Vista
It seems the WMF patch that was recently released for Windows 2000 and XP (and 2003) has been ported to Microsoft Windows Vista Beta…. This makes it the first security patch for Vista. eweek has an article on the issue. So, if you’re beta testing Vista, get it updated ASAP. Hopefully though, if you’re beta-testing it’s not a production machine and no great loss if you get infested with beaucoup spyware….
However, if I had spent a good deal of time preparing a test system for Vista, it would be a pain in the neck to have to format and reinstall after a spyware infestation.
Anyway, the Microsoft page for the update is here with a brief description and download link.
