Early adopters of Microsoft’s next operating system won’t face debilitating bi-hourly shutdowns or be forced to clean-install the release candidate until July 1, despite an email that went out over the holiday weekend setting a June 1 deadline. The date for the shutdowns to begin is actually July 1, a month before the Windows 7 beta program expires, according to Microsoft Windows blogger Brandon LeBlanc, who posted the information early Tuesday to the company’s Windows 7 blog.
