AWS drs high security documentation change

Service: drs · 2026-02-16 · Security-related high

File: drs/latest/userguide/Supported-Operating-Systems-Windows.md

Summary

Updated Windows OS support matrix: Removed Windows 2003 details, added end-of-life warnings, and consolidated unsupported features.

Security assessment

Explicit removal of Windows 2003 support (including TLS 1.2 incompatibility) and added end-of-life warnings for outdated OS versions. Running unsupported OS creates security risks due to unpatched vulnerabilities.
