Service Pack 1 for Windows 7 and Windows Server 2008 R2 has hit the Release to Manufacturing (RTM) milestone. The build reportedly went final on January 18, 2011, according to Techarp.

The warez group WZ ZUKO has already started distributing this build to various torrent sites. It's important to note that Microsoft has yet to confirm that SP1 has hit RTM, so there are no details regarding a roadmap for the Release to Web (RTW) plan. "Microsoft has not released Windows 7 and Windows Server 2008 R2 SP1, though we are on track for a Q1 release, as we previously announced," a Microsoft spokesperson said in a statement.

Here are the details of the reportedly final RTM build:
