Symptoms

Affected Operating Systems:

  • Dell ThinOS 10
  • Dell ThinOS 9

Cause

Due to security concerns, Amazon is adding enforcement that prevents clients with AWS agents older than 2025.0 from attaching to Amazon Workspace environments starting January 2026.

Resolution

Reference the list below for appropriate corrective actions.

  • ThinOS 9 clients that are still eligible for quarterly software updates should upgrade to ThinOS 9 2508 and use the AWS 2025.0 package.
  • ThinOS 9 clients (legacy Wyse clients) that are no longer eligible for quarterly updates should contact Dell Support and request a solution.
  • ThinOS 10 clients should update to the AWS 2025.0 update prior to January 2026. The AWS 2025.0 update is available at Support for Dell ThinOS. For more information about installation, refer to the AWS PKG file’s installation instructions.
