Microsoft will release Windows 10 on June 29, 2015. Windows 10 will be available as a free upgrade for users of Windows 7 and Windows 8.1. Windows 10 will also be available to Caltech students through the Microsoft DreamSpark program (http://msdnaa.caltech.edu). Faculty and staff will be able to download Windows 10 from the http://software.caltech.edu webstore several days later.
Please note that Windows 10 is a major product release that includes significant changes to the user interface, functionality, application/document compatibility and system performance. IMSS strongly recommends that customers evaluate Windows 10 on test systems before installing them on any production systems to avoid any interruption of work-related computing tasks. While IMSS can provide best-efforts support for Windows 10, we cannot guarantee compatibility with the systems and services you most commonly use. IMSS will continue to evaluate Windows 10 and will post updates as they become available.
