Well, I got it straightened out. All the default profiles and temperature info is back. I had to uninstall AWCC with the AWCC Package Manager (the one that previously failed to install a working AWCC), and then restart, and reinstall using that same package manager. Before doing that I updated my BIOS, but I can't imagine that had anything to do with it. This stuff definitely seems finicky in my history of using it, but I'd never seen this happen before. Thanks for the help anyway.
I did a clean install of Windows 11 and reinstalled AWCC (Alienware Command Center) etc. When I open it it keeps trying to install Alienware OC Tools or something, and it’s stuck in a Windows Hello loop telling me that an error occurred, and that I already own that. I can’t locate it in Microsoft Store. My main concern is that I have no overclock or fan speed profiles. I only have Balanced for thermals, and I cannot create a new one, either. AWCC is totally missing what should be there. Please help! Thanks!
