This update solves two issues and should be installed.

The first problem that is solved is that the security tab shows the spyware/malware status on Windows Vista SP1 boxes “incorrectly”, and I like to have that information correct for some reason.

The second problem is that when register a domain name with GoDaddy.com as the provider it fails. Not fun to be GoDaddy :-)
(Make sure that you install this patch before running trough the To-do list if you are going to use GoDaddy as a provider)

MS official KB can be found here, the patch is available from http://update.microsoft.com (and WSUS)
