MS09-065 – Tracking a New Issue on Windows XP

Good morning folks!  Sorry that today’s post is a little later than usual.  We’ve been tracking an issue related to Microsoft Security Bulletin MS09-065 ( KB Article 969947 ) on Windows XP.  You may notice odd behavior including system hangs, bugchecks or even blank desktops during RDP sessions following the installation of this patch.  Customers have reported that removing the patch restores system stability.  The fix for this issue is fairly straightforward:

• Reboot the system into safe mode
• From within Add/Remove Programs, uninstall the patch.  The patch will be listed as Security Update for Windows XP (KB969947)
• Restart the system in normal mode

At this point, the steps within the KB Article indicate that you should remove your video card drivers / management suite and then re-install the patch before updating your video drivers to the latest version provided by the manufacturer.  There have been some customers who have updated the video card drivers first and then re-applied the patch successfully.  In either case, the key is to ensure that you get your video card drivers updated to avoid stability issues with this patch.

That’s all for today – a short post, but one that we wanted to get out there since we are seeing quite a few customer incidents on this.  Friday’s post will be … something different.  Until next time …
