Enable Touchscreen Capabilities Fresh Windows 8.1 Install - Dell XPS 15 9530

So I got one that stumped me. I just got a new Dell computer yesterday and as I've done the last 10+ yrs, I install a fresh retail copy because, like most people, hate dealing with their extra software and prefer a clean install so I just don't have to deal with uninstalling, etc. Turns out that may have been a bad idea. After the install was done, touch no longer works on the screen. I have installed the drivers from Dell's site to no avail. The device manager has no missing hardware and all windows updates are current. My system info recognized there is pen and touch capability. I also checked the Pen and Touch settings under the touch tab and that all seems to be correct (all I have to compare those settings to is a Dell Venue 8 Pro, but they are the same). My suspicion, and I could be way off on this, is that I'm using a retail copy instead of the OEM copy of Windows 8.1. I tired a Pro and a regular retail (yes, both legal copies) and neither worked. I do know the new computers have the key embedded in the uefi (bios). I have tried installing with and without overriding the embedded key. But that is the only thing I can think of and I'm hoping you guys had some ideas or someone else has had this problem and can help me troubleshoot. Model: Dell XPS 15 9530 with the QHD+ Touch Monitor. Update: I've ruled out retail vs oem fresh installs. I tried an install using the Dell backup/restore discs. Same deal. It's gotta be some sort of setting, or driver that's not on their site.
