There will be updates for the Beta through Windows Update in the coming months yes.. There is already one update for Win 7 Beta.. the one that addresses the mp3 corruption issue.
Windows Update gave me 6 so far; 2 the first time then 4 a couple of days later. The first 2 included a driver for my Realtek 8187b network adaptor. Sweet.
Yes people you should all expect updates to occur throughout the duration of the Windows 7 Beta experience. This post is kinda getting pointless so i am closing the thread. Thank You!
