I purchased this adapter along with the Xbox One Limited Edition Halo 5: Guardians Wireless Controller to use on my gaming mini PC. Straight away, this adapter loses a few points for only supporting Windows 10. I guess this is yet another way Microsoft is trying to encourage people to adopt that operating system. That being said, once you do a bit of work shutting down its privacy-invading "features," Windows 10 isn't terrible. In fact, from an overall functionality perspective, I think I actually prefer it to Windows 8.1, however I won't be rushing to install it on other machines in my household.
Back to the controller adapter. Getting it set up on my PC wasn't the plug-and-play experience I was expecting. At first, I thought it was dead right out of the box. The little light on the side wasn't illuminated, and my controller wouldn't pair with it. It turns out that my Windows 10 installation did not have the proper drivers for this device. It was recognized as being connected to the computer, but Windows device manager reported it as "XBOX ACC" with the dreaded yellow exclamation mark next to it.
Because Microsoft claims this device should be plug and play in Windows 10, they don't have a place on the Xbox portion of their website to download a driver. That doesn't mean a driver doesn't exist for you to download; it simply requires you to take a few extra steps, so if your Xbox One wireless adapter is not working on your Windows 10 PC, try the following:
1) Use Internet Explorer or the Microsoft Edge browser and visit catalog_dot_update_dot_microsoft_dot_com (remove the underscores and replace "dot" with periods). You must use IE or Edge - other browsers will not work.
2) Search for "xbox wireless" using the box at the top of the page. It will bring up a list of about 17 items. You will want to select "Microsoft - Other hardware - Xbox Wireless Adapter for Windows" version 18.104.22.168, dated 11/3/2015. Add the file to your download basket and save it to your desktop.
3) The download comes in the form of a Microsoft catalog file with a .cat extension. I used a freeware program called 7Zip to extract the driver. After doing this, go into device manager, select the unknown XBOX ACC entry, then update driver. Choose the option to manually install the driver and use the wizard to browse to where you extracted the .cat file. The driver should install, and then you can pair your controller per the setup guide.
The controller now works perfectly. It was a little bit of a hassle to get past the initial setup, but it was definitely worth it. Now I can play games from my couch without having a lengthy USB cable running across the floor.
