If you're a reader of my blog, you'll remember that way back in 2011 I wrote a blog post that shows folks how to slip stream service pack 1 of SharePoint 2010 into the RTM media. Those instructions work for a service pack or cumulative update. With the release of Service Pack 2 for SharePoint 2010, I just want to remind everyone that those instructions do indeed still work. There is one gotcha. They won't work for SP2 on Windows Server 2012, due to some changes in the prerequisite installer. You'll have to download a build that already has SP2 slipstreamed for Windows Server 2012.
