Windows 7 and Windows 8.1 PC gamers can now play games with the Xbox One controller wirelessly. Microsoft has revealed the previously released Xbox Wireless Adapter, which only supported Windows 10 PCs when it was first launched, now supports the two older Windows operating systems as well.
The news was revealed by Microsoft's Xbox Live programming head Larry "Major Nelson" Hryb via his Twitter feed. Hryb didn't mention how this new support was added, but we would assume it's via a firmware update for the adapter. In any case, this should open up the Xbox Wireless Adapter to a much bigger audience of PC gamers who have yet to make the upgrade to Windows 10.
