Back in the good old days (aka a few years ago) Windows Update tended to be something that just… worked. You’d take a fresh Windows install, pop it through the update process and after a bit of chugging you’d get a fully patched OS.
Recently Microsoft seem to have made a bit of a mess of things and I’ve spent far too much time forcing recalcitrant machines to do what should be a simple task.
Hopefully once the cumulative updates start rolling everything into the monthly patch cycle this post may become irrelevant. Until then here’s the quick way to persuading a Windows 7 / 8.1 machine through the Update process…
High CPU hotfix
Install this one first if you’re faced with a particularly out-of-date installation otherwise you’ll be stuck for days “searching for updates” while your CPU goes crazy (100% utilisation) for very little return…
Windows Update Agent
Next install this to update your updating software in order to download new updates (!)
Reset Windows Update Agent script
Sometimes Windows Update still won’t work in spite of the patches above so run this script from TechNet to reset the Windows Update subsystem in case something has gone awry
Round trip limit exceeded
Despite all of the above Windows Update can still fail because of a hard-coded limit in how it talks to WSUS (this only applies to managed Windows desktops rather than home users). In which case you need to take advice from this song…
“you can get it if you really want but you must try, try and try, try and try… you’ll succeed at last”
Basically just keep clicking the retry button until WSUS gets through enough trips to serve you all the updates Windows needs.
You may also be able to speed things up by cleaning up your WSUS server, which can be aided via this very useful script
or this one…
Now that’s sorted you can make yourself a cup of tea and wait for that progress bar to crawl across the screen! Will be interesting to see how the cumulative update process goes but if it means an easier way of rolling an out-of-date machine up with one single download then it’ll have some benefits for convenience albeit at the expense of granular control… swings and roundabouts I guess…
