AWS AWSEC2 documentation change

Service: AWSEC2 · 2025-05-31 · Documentation low

File: AWSEC2/latest/UserGuide/install-wsl-on-ec2-windows-instance.md

Summary

Added Windows Server 2025 to supported OS list and removed a warning about Virtualization-based Security (VBS) causing boot failures on Windows Server 2025 instances.

Security assessment

The removed note addressed system stability concerns rather than security vulnerabilities. While VBS is a security feature, the change removes a compatibility warning without introducing new security documentation or addressing a disclosed security issue. This appears to be a documentation accuracy update.

-When you install WSL, it automatically enables Virtualization-based Security (VBS) on instance types that support it. EC2 instances don't support VBS for Windows Server 2025. The system could fail to start after a reboot if it's enabled.
