Upgrade Windows Server 2016

Background

Microsoft has ended Mainstream Support for Windows Server 2016, Windows Server 2019, and Windows 10. These operating systems no longer receive free incident support or security updates from Microsoft. Although EDS Enterprise Edition still supports creating cloud computers with these operating systems and continues to provide EDS-level compatibility support, be aware of the associated risks before you choose an older OS version.

Impact after Windows Extended Support ends:

• After the Extended Support end date, Microsoft will no longer provide any software maintenance or support, including bug fixes and feature updates.

• Cloud computers that were created in EDS Enterprise Edition with these operating systems will continue to run after the Extended Support end date. However, certain features such as dual-monitor support may be limited. We recommend that you upgrade to a newer OS version as soon as possible to ensure security and stability.
