That’s right, according to a beta community, the Beta 1 build of Windows Code Name: “Longhorn” (note that the build won’t be tagged as “Vista”) will be released to testers tomorrow, Wednesday. The number will be about 5112 and MSDN Subscribers are going to be able to get it by the targeted date, August 3rd.

The build’s downloading will be done in stages, in order to preserve the servers from hammering. And people who expect invites for the beta shouldn’t worry, either - thousands of invites are sent each week. Current “pending” testers should get their status changed to ‘Active’ or ‘Approved’ by tomorrow morning.

BTW, Beta 1 of the WinFX SDK and Avalon is going to be released by Microsoft tomorrow, too. You can expect two little articles on both themes here and/or on AeroXperience soon.
