Microsoft released a beta refresh of its Windows 7 and Windows Server 2008 R2 SP1 to selected PC and Technology Adoption Program (TAP) partners, company officials confirmed via Tweet on August 30. The refresh build is said to be Build No. 7601.17077 — available to a select group of testers on August 27. There’s no word (so far) on whether there is anything new in that refresh. “A private interim release went out Friday as part of our normal feedback loop with a small group of our testers – our TAP and OEMs,” a company spokesperson told.
