Microsoft told us to clear our pipes for a hefty download on the 22nd of February, and sure enough, the software giant is delivering. Windows 7 and Windows Server 2008 R2 Service Pack 1 is now available for public consumption, with the company also confirming that 7601.17514.101119-1850 is the final RTM. We'd bother telling you more, but we know you've already dug into the source link in order to get your download a-hoppin'. Just make sure you uninstall any pre-releases of SP1 before doing the deed with this one, and if you're updating just a single PC, you're probably better off waiting for everything to flow through Windows Update. Your call, though.
