What is the 'What Version of Windows Do I Have' tool?
This tool detects your Windows version using User-Agent Client Hints (platformVersion) and User-Agent (Windows NT x.y). It shows whether you're on Windows 10 or 11, the Windows NT version, and CPU architecture (x64/ARM64).
If high‑entropy UA hints are available (Chromium), it distinguishes Windows 10 vs 11 accurately. Otherwise, it provides the best guess based on NT version (10.0 ⇒ Windows 10/11).
