Microsoft has reportedly signed off on the final Build of the first upgrade to Windows 7. The information comes from a third-party source that has been right on numerous occasions in the past, and that is also promising to leak the Windows 7 Service Pack 1 RTM development milestone. It appears that the Redmond company has wrapped up the development process of Windows 7 SP1, and that it’s gearing up for the next stage, distribution.

While there’s no telling when end users will get the RTM bits of Windows 7 SP1, Wzor indicates that Microsoft partners are the first in line to receive the upgrade in the immediate future.

It appears that the final Build string number for Windows 7 SP1 RTM is 6.1.7601.17514.101119-1850.

This release was previously a RTM-Escrow Build for the service pack, and as no issues were discovered with it, it graduated as the fully-fledged RTM.

Of course, since the latest releases of Windows client and server are joined at the hip, Windows Server 20087 R2 SP1 RTM is also Build 7601.17514.101119-1850.

Microsoft has yet to confirm that Windows 7 SP1 has been finalized. In fact, the software giant has said very little about the development process of the upgrade, and even less after the service pack hit the Release Candidate (RC) milestone.

The Redmond company did confirm officially that Windows 7 SP1 RTM will be provided to customers by the end of March 2011, and it appears that it’s right on track to doing so.

So far, an official general availability deadline for Windows 7 SP1 RTM hasn’t been provided to the public.

At the time of this article, only information on Windows 7 SP1 Build 7601.17514.101119-1850 RTM had been leaked in the wild, with the actual bits not yet available for download.

Windows 7 Service Pack 1 (SP1) Release Candidate (RC) Build 7601.17105.100929-1730 and Windows Server 2008 R2 Service Pack 1 (SP1) Release Candidate (RC) Build 7601.17105.100929-1730 are available for download here.
