A post to a Microsoft blog in Russia may have prematurely announced the availability of Windows 7’s first service pack. Microsoft says the claim is inaccurate.

The awaited first service pack for Windows 7 may not be far away, according to a posting on a Russian Microsoft blog.

Late last week, a Microsoft (NASDAQ: MSFT) TechNet blog, titled “Russian Windows Virtualization Discussion,” ran the headline “Released Service Pack 1 for Windows 7 and Windows Server 2008 R2.”

The rumor mill kicked into high gear, with multiple sites stating that SP1 has already begun delivery to OEMs, based on this post: “A more detailed description with links to download wait for tomorrow!” the blog post said.

“Microsoft has not released SP1 to OEMs at this time, though we are on track for a Q1 release, as we previously announced. The comments made in this blog entry included some inaccuracies,” an update to the blog post said on Jan. 14.
