Elastic Desktop Service:Upgrade Windows Server 2016

Background information

Microsoft has discontinued mainstream support for Windows Server 2016 and Windows Server 2019, meaning free incident support and security updates are no longer provided. While EDS Enterprise still supports creating cloud computers with these OS versions and offers compatibility assistance, it is important to note that using unsupported or soon-to-be unsupported OS versions poses risks and requires careful consideration.

Impacts of Windows Server's Extended Support ending:

• Once Extended Support ends, users will no longer receive software maintenance or support from Microsoft, including bug fixes and feature updates.

• Cloud computers created in the EDS Enterprise console will continue to function after the Extended Support period ends, but some features, such as dual-screen, may be limited. For better security and stability of your cloud computer, please upgrade to the latest version as soon as possible.

  If cloud computers cannot access the Internet, the following solutions are provided:

  • By default, cloud computers in the Chinese mainland regions can access the Internet. If a cloud computer cannot access the Internet, see What do I do if a cloud computer cannot access the Internet?

  • Cloud computers in the China (Hong Kong) region and overseas regions can access the Internet only after you complete the enterprise real-name verification, enable the premium bandwidth feature, and associate premium bandwidth plans with office networks. For more information, see Enable a premium bandwidth plan and Attach a bandwidth plan to or detach a bandwidth plan from an office network.

• When you upgrade the OS of a cloud computer to Windows Server 2022, make sure that the system disk on the cloud computer meets the following requirements:

  • The available space is greater than or equal to 20 GiB.

  • The available space is greater than the size of the C:\Windows directory.

  Note

  If the available space cannot meet the requirements, you need to free up more space or increase the system disk. For more information, see Increase the disk capacity.

Usage notes

• Cloud computer shares do not support Windows Server upgrades.

• During the upgrade, cloud computers automatically enter the Stopped state. Make sure that all data on cloud computers is saved in advance.

• The upgrade takes about 45 minutes.
