The Return Of The Microsoft Patch

This morning we re-released our August security update (MS06-042) for IE 6.0 SP1. This update is available through all of our normal release channels including Windows Update, Automatic Update, Download Center and our deployment tools such as WSUS.

As I mentioned Tuesday, the original release of MS06-042 introduced a new security vulnerability for IE 6.0 SP1 users. This re-release fixes that vulnerability. We recommend all IE 6.0 SP1 customers install the update immediately. Users running Windows XP SP2, Server 2003 SP1, IE 5.01 on Windows 2000, or any of the IE7 betas, The IE7 Release Candidate 1, or Windows Vista are not affected and do not need to take action.

First, IE7 RC1 setup automatically detects and uninstalls previous IE7 betas before trying to install IE7 so you don't have to. We'll post more detail on the install/uninstall process very soon.

Second, IE7 RC1 will automatically detect add-ons with known stability or compatibility problems so that end users can easily get a newer version or temporarily turn the add-on off. The most common cause of the "IE7 installed but won't run" problem reports we've gotten was old versions of some toolbars. We've worked closely with toolbar vendors to make this experience better.
