I don't know if this will help in this instance, and I have no experience with XBOX One controllers,
but below is what I had to do when trying to install a Logitech controller that has both XINPUT and DINPUT
(even though I had already manually installed the XBOX driver).
I don't recall exactly what was done, but...
- If you don't still have your XBOX software installer download it again.
- Go to Device Manager and R/click on your XBOX Controller
- Click on Update Driver Software
- Select the Browse My Computer option.
- Browse to the location you have saved the driver installer to and click Next to install.
Or...
- Select the 'Let Me Pick' option. Your previously installed XBOX controller driver should
be on the list, so just click on this and select Next.
[ Cross fingers and do a quick highland jig for luck. ]
[ EDIT: "I guess I should note that I had been using a Wireless Xbox 360 Adapter with a legit 360 controller"
Try uninstalling the 360 driver, and any other related software. Reboot before trying the XBOX One controller again ]
"I do not want to do a clean install of windows 10, as I'd lose a lot of my games that I've downloaded. It would be a pain in the **** to re d/l all of them. But if its the only option, then I guess I have no choice."
Reinstalling Windows is very rarely necessary, and is really just a lazy way out that, in the end,
can take longer than pushing on with more searching and troubleshooting.
However, in the event that Windows does get fully stuffed (or HDD/SSD fails ) having a clone of your
Windows can save lots of time and pain.
- The next best option is to do a 'Repair' reinstall, as this does not wipe the Registry, so your games and software
are not affected.
- If your games are installed to the default location (Program Files x86) a clone is more problematic because
doing a clone with hundreds of games on the same partition as Windows can take a very long time,
but if you use a separate partition or HDD for your games, keeping a recent clone of Windows on
and external drive can be a life saver.
The games should also be copied to an external HDD, but because most games don't go through many changes,
(Automatic Steam updates and modding excepted) this does not have to be done regularly.
The only thing you need to be careful of is that you use the same drive letter/path should you need to
restore your games from the external disk .
