So there never was a Service Pack 2 for Windows 7, however... there plenty of sites taking advantage of that. There is however a Convenience Rollup Package that can be installed along with or after Service Pack 1 that includes all the updates that came out after the year 2011. The installation is straight forward as long as you run the installs as an administrator. Downloads can be accessed on the Microsoft update catalogue site, and as always there are direct links below to the 64bit and 32bit Convenience Rollup Package.
