The SP1, as stated by Microsoft, will be mainly a rollup of already-released hotfixes.
Earlier in the month, Microsoft spokesperson Gavriella Schuster, said the Windows 7 Service Pack 1 official beta was set for a July launch.
She also explained the SP: "It will not contain any new features that are specific to Windows 7 itself. For Windows 7, SP1 will simply be the combination of updates already available through Windows Update and additional hotfixes based on feedback by our customers and partners. In other words, customers can feel confident about deploying Windows 7 now!"
Just yesterday, the software giant announced it was selling seven Windows 7 copies per second, with 150 million licenses sold in just 8 months.
