UH Microsoft Windows 8.1 Update Information

If you're already running Windows 8, the Windows 8.1 Update is free. For computers that are NOT currently licensed or eligible for Windows 8, you will need to purchase the upgrade license if you wish to move up to Windows 8.


     Information Technologys Services (ITS) does NOT recommend the upgrade to 8.1 and will not be supporting Windows 8.1 at this time.

McAfee has not yet made available a compatible antivirus for Windows 8.1. VSE 8.8 patch 4, when released, will support Windows 8.1.

Also, Internet Explorer is automatically updated to version 11 with Windows 8.1. IE 11 is not currently available for Windows 7, Windows 8, or Windows RT. Compatibility testing has not yet been done to ensure that all ITS-managed web applications will work on this browser.

We will update the advisory as testing is completed and new information about compatibility becomes available.
