Windows 2008 R2 Updates taking a very long time to install

    Question

  • Hi,

    A bit of a strange one that we can't understand :) A bit of a long story too..

    Recently we have been experiencing problems with very slow installation of updates on Windows 2008 R2. After some updates were applied, the server rebooted and on the console displayed a black DOS type background with the message "applying update 245 of 23610" at the rate of about 1 per second. 

    This took server hours to complete before the process finally finished and the server continued to boot. Naturally during this process the server was unavailable causing no end of problems and concern. After a lot of searching we thought the issues might be fixed by installing SP1, which we did and it looked like the issue was fixed.

    Unfortunately after a couple of weeks the problem returned, and after a reboot we got the slow applying update message again for several hours. As this server was running on a virtual platform we decided to build another server for testing purposes and were able to replicate the issue with a fresh template/build 

    After days of tests both from our environment point of view (storage/networking etc) and a windows point of view, the problem was traced to KB2533552 http://support.microsoft.com/kb/2533552 needing to be installed before any other updates and even before SP1. 

    The most confusing aspect is why installing this particular update fixed the issue as it appears to be a fix for SP1, not updates prior to SP1.

    I know it's a lot to ask, but has anyone either had a similar experience with slow updates or even better can explain why this update fixed the issue. 

    Thanks in advance
