I keep trying to fix this driver issue I have been having. Today the Windows 10 Insider Preview 17661.1001 (rs_prerelease) update appeared but every time I attempt to download it, I find myself stuck at 80%. I was somehow able to just run a BIOS update so that wasn't affected. But I cannot use any bluetooth devices right now. I also cannot charge my phone with my laptop or use my xbox controller. I really don't want to have to reinstall everything or anything. I just want to update my Dell XPS 15. I'm on fast updates with insider if that helps. Thanks.
