Windows 11+ supports x86_64 emulation, but Windows 10 only supports x86 emulation. Advantages of reporting ARM64 Windows 11+ as x86_64: * Sites that offer software downloads will know that the client is capable of running x86_64 software. * Reduced fingerprinting entropy because ARM64 Windows 11+ users' UA string will match the UA string of the ~80% of Windows Firefox users running x86_64 instead of the ~20% running x86. * Some sites disable features for 32-bit clients, such as Google Meet requiring 64-bit to use wasm visual effects: https://github.com/WICG/ua-client-hints/issues/217#issuecomment-878537336 https://support.google.com/meet/answer/10058482?expand_all_zippies=true#requirements&zippy=%2Cwhy-cant-i-use-the-change-background-option%2Crequirements-to-apply-visual-effects-on-computer The browser_navigator.js test is not actually run on ARM64 Windows in automation, but these test changes would make the test pass on ARM64 Windows 10 and 11 if this test ever is run.
