How to upgrade Internet Explorer for all domain users.

You might want to look at utilizing the Microsoft Windows Server Update Services (WSUS) software package.

Microsoft Windows Server Update Services (WSUS) enables information technology administrators to deploy the latest Microsoft product updates to computers running the Windows operating system. By using WSUS, administrators can fully manage the distribution of updates that are released through Microsoft Update to computers in their network.

After quick research, I did discover that older IE7 releases had an interactive WGA check embedded in it. I found on the Microsoft site a new release that no longer has the WGA check embedded in it, thus might be able to be pushed to your client workstations.

Hi MW

I am having problems with the WSUS on my SBS Server. Apparently it was not correctly installed or some components are missing. Is there a way to remove WSUS and reinstall it from scratch?

Thanks

Hi Guys, I have installed WSUS and I am haveing a hard time configuring it. Isn't there an alternative to upgrade IE without WSUS?

Thanks

I found this EE article about using the Internet Explorer Administration Kit for deploying:

If WSUS isn't out of the picture, I also found this Microsoft Support article:
