Windows Vista Vista security update packages via Windows Update

[muckshifter]

Tuesday 8 January, we are releasing several non-security update packages via Windows Update. The updates include the regular monthly Malicious Software Removal Tool and Windows Mail Junk Mail Filter, two updates in our regular series of Windows Vista updates (KB943302 for application compatibility and KB943899 for reliability and performance), and one update of particular notice: KB935509. Similar to previous updates that enhanced Windows Vista’s performance and reliability, these updates will be distributed automatically through Windows Update.[font=verdana,geneva]Tomorrow’s KB935509 release is a little different than past updates. It is a prerequisite for installing SP1 and is applicable only for Windows Vista Ultimate and Enterprise users, because it only affects versions of Windows Vista supporting BitLocker Drive Encryption. [/font]

[font=verdana,geneva]This update modifies the boot loader to enable successful install or uninstall of the service pack if the PC uses BitLocker encryption. We’re releasing it now to lay the groundwork for future updates and to eliminate any extra reboots by installing it along with updates that already require a reboot. For more information on the update, see KB article KB935509 (which will be posted on Tuesday morning).[/font]

[font=verdana,geneva]In addition to KB985509, there are two other updates that will be prerequisites for Windows Vista SP1, for all versions of Windows Vista. They will be released at a later date and will improve the installation experience and reliability for the service pack as well as for individual update packages. [/font]

[font=verdana,geneva]SP1 development and testing efforts are continuing as expected and we remain on track for its release later this quarter.[/font]

My bold emphasis ... however, reports are coming in that some, like me, have this downloaded and installed ... you will be pleased to know, it shouldn't cause any undo concerns.

we noticed earlier today that in a small number of cases, this update was offered for installation on all Windows Vista editions instead of for Ultimate and Enterprise only, so we adjusted the logic to redefine that behavior. Systems with Windows Update set to download and install updates automatically will not install it even if it has already downloaded, so ultimately, most people will not be affected. If you happen to already have installed the update on your system it will have no negative impact. It was designed to install on all versions of Windows Vista but is not required on any other version for SP1.

So, that's OK then ...
