Microsoft Enrollment for Education Solutions (MEES)

Welcome to the Microsoft Enrollment for Education Solutions (MEES) (formerly Microsoft Campus Agreement) web site for the Texas Tech University Health Sciences Center.

This site contains information regarding TTUHSC Site License Agreement with Microsoft. It provides select Microsoft software to all students, faculty and staff of the TTUHSC for personal use. This agreement encompasses all of the TTUHSC campuses and includes distance-education students as well.

Some software media is available to download free of charge. Due to licensing changes in the MEES, newer Microsoft software titles including Windows 7 Ultimate, Office Professional Plus 2010, Windows 8 and Office Professional Plus 2013 are only available on DVD media. The cost for each software title on DVD media is $10.00 US.

Select Microsoft software is also available to TTUHSC departments for institutional use through the Texas Tech University System's Site License Agreement with Microsoft.  Please contact the IT Solution Center or submit a STARS work order requesting assistance with your new computer purchases and with any upgrades or migrations to supported software.
