IE11 on Windows 10 gets detected twice

[nerdbeere]

I think the issue here is that there are two IE11 binaries on Windows 10. One is a x86 binary the other one a x64 binary.

Also see the output generated by win-detect-browsers:

[ { name: 'chrome',
    version: '58.0.3029.110',
    type: 'chrome',
    command: 'C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe' },
  { name: 'firefox',
    version: '53.0.3.6347',
    type: 'firefox',
    command: 'C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe' },
  { name: 'opera',
    version: '45.0.2552.888',
    type: 'opera',
    command: 'C:\\Program Files\\Opera\\Launcher.exe' },
  { name: 'ie',
    version: '11.0.15063.0',
    type: 'ie',
    command: 'C:\\Program Files (x86)\\Internet Explorer\\iexplore.exe' },
  { name: 'ie',
    version: '11.0.15063.0',
    type: 'ie',
