Whilst troubleshooting slow printing issues, I stumbled across the following blog post: http://blogs.technet.com/b/askperf/archive/2012/03/16/print-update-rollup-available-for-windows-7-amp-windows-server-2008-r2.aspx
I was surprised to read this in the comments:
At this time there are no plans to make this available on WSUS
Really?! If it is “designed to reduce known issues such as printing performance, print spooler crashes, connectivity to print queues, and print driver installation” then why would Microsoft not distribute this through the normal channels?
You can get the updates at http://support.microsoft.com/default.aspx?scid=kb;en-US;2647753 but don’t go blindly rolling this out; test first!
