Hey @jbright , Thank you for bringing this up, the warning you're seeing is correct - version 4.0+ of the agent requires Windows 10 22H2 (OS build 19045) and above or Windows Server 2022. I have asked the team to update the Supported Operating Systems KB to reflect this, there's also a request to improve the error that is displayed (to include a specific callout for Windows Server). For Windows Server 2016/2019, you'll need to remain on agent version 3.8.2. Cheers, Connor
