 As yawning noted in #17550 the default GUI font changed across Windows
 versions:

  * Windows XP -> `MS UI Gothic` (Not sure if this needs to be localized,
 don't have a box with this)
  * Windows Vista/7 -> `メイリオ`
  * Windows 8/8.1 -> `Meiryo UI`
  * Windows 10 -> `Yu Gothic UI`

 This might aid in fingerprinting JA users which are on Windows.
