End of Support for Observer components on Windows 7 Operating System
Since the End of Support date for Windows 7 in January 2020, VIAVI Solutions has provided best effort support for platforms using that operating system. As of the 18.3 release, however, we will no longer provide support for systems using Windows 7. Because of certificate validity timeframes, systems running on Windows 7 SHOULD NOT UPGRADE beyond the 18.2 release of Apex or GigaStor. This mainly affects systems using the Gen2 range of hardware. If you are affected by this end-of-support event, please contact your VIAVI Solutions sales representative to discuss your go-forward options.

End of Windows 2008 Support
Version 17.5 of Observer will drop support for Windows 2008 and Windows 2008 R2. 17.5 is scheduled to be released around September or October 2018.

For customers running VIAVI appliances that have Windows 2008, an upgrade image to Windows Server 2012 R2 is available for purchased (Part number: SYS-IMAGE-WIN2012R2). Please contact your sales representative for pricing. See Security News.
