Got the exact same issue that happen suddenly to me last night, same desktop. Did the same thing you did but I'm getting nowhere.

1. I've already tried to restore to a previous point where it said windows update and same issue.

2. Tried restarting in safe mode to reinstall CC and nothing. I am running windows 10 on an Alienware Aurora R6.

1. That almost never works, and if fact ... sometimes makes things worse.

2. I think (maybe) you can uninstall CC from Safe-Mode, but I don't think installing new version will work from there. I think you have to be inside full-Windows.

I'm still running Alienware Command Center v4.6.20 ... so maybe try a clean-install of that version.

If that doesn't help, maybe try the new v4.8.23.

Remember these Alienware Command-Center tips:
(These tips have served me well, for like 8 years now).

- Never upgrade from inside CC itself (always clean-install a fresh version)
- Always uninstall old version and REBOOT, before installing any version
- After downloading the installer, I always use Windows-Explorer to "UnBlock" the file before using it.
- Try disabling Window's Fast-Startup feature. If you boot from a SSD, you won't even notice.

This has never happened before, but it looks like my Aurora-R6 stumbled a bit auto-installing and auto-rebooting ... after a pushed Windows-Update last night.

I just shut-down and rebooted and then everything was fine. I didn't think much of it, but in-light of this thread, I guess I will collect some data and then write-up the event, and post it here later:

So, how's it going guys ?

I wrote-up our incident here. It was weird and a little scary but everything seems fine for us (a reboot fixed it).

I was getting frequent pop-up messages from User Account Control, Command Center, Verified publisher Microsoft Windows after a Windows update.  I finally got rid of these buggy pop-ups after uninstalling and re-installing Alienware Command Center.  Deja-Vu. The buggy pop-ups are back.  I uninstalled and re-installed Alienware Command Center.  The pop-ups ceased again.  But, this time, I think the Alienware Command Center is in conflict with a recent Windows update.   I can open Alienware CC but, when I click on Thermal Controller, the program shuts down.  I ran the BIOS update but, I think it was the same version.  I even tried holding the power switch in (unplugged), for 30 seconds.  I've tried uninstalling and re-installing Alienware CC twice.  No change.  Thermal Controller still crashes.   My system is a Dell Alienware Aurora R6.   I've had so many problems with this software, having to R&R it all to frequently after Windows updates, I wonder just why I need it.  Will my system cool itself properly without it?

See my URL above.

My Aurora-R6 is still on Command Center v4.6.20 and it works fine. Be sure AW-CC update option is OFF.

Yeah, so 1703, 1709, and now 1803 ... all fine.
