EXACT SAME ISSUE

I had the same issues and updated mine and then it really messed it up, noticed my audio controls were gone and the performance monitors were gone.  I ended up uninstalling all the Alientware stuff and installed Alienware-OC-Controls_14PN4_WIN64_1.2.32.1210_A00 and App_DT_OCControls1.0.5.0_W10_Setup_4K9TW_ZPE and Realtek-ALC3266-Audio-Driver_0V67W_WIN_6.0.1.8098_A04

I don't recall where I got each of those but Googling them should find them.  Evidently Windows or SupportAssist updates and also specifically Realtek drivers will mess the AlienWare stuff up so gotta be careful at updating those in the future :/

When you installed this:

"Alienware-OC-Controls_14PN4_WIN64_1.2.32.1210_A00 and App_DT_OCControls1.0.5.0_W10_Setup_4K9TW_ZPE and Realtek-ALC3266-Audio-Driver_0V67W_WIN_6.0.1.8098_A04" 

it let u overclock and control fan speed?

Same :/

No I don't think we can do that on this laptop.  I think there's conflicting information out there about this.  I just noticed when I had removed and reinstalling Alienware OCC stuff I was missing audio controls, and the monitors that shows me the CPU/GPU speeds/temps but found a thread elsewhere that said installing the Realtek drivers will remove this stuff so not to do so.  

Come on DELL Fix this already! No Alienware support after installing the latest drivers
