Just got the word that Windows 7 General release is now available on the Windows 7 website. Also make sure you patch the release for the mp3 flaw.
I also noticed in the release notes that if you have an iPhone and install the 64 bit version of Windows 7, and you install the 32-bit version of iTunes and your phone will not sync up properly. To get the 64 bit version of iTunes, go to http://www.apple.com/support/downloads/itunes801forwindows64bit.html.
I am also looking for an antivirus for Windows 7 and when I do find one, I’ll post a link.
