Was just checking in to see if there was more activity here.  Since there isn't any word from EVGA yet, I opted to uninstall KB4515384 as  suggested and can confirm that removing this single update resolved my crash.  Looks like it's proving to be a rather problematic update in general.  Not sure what Microsoft's plans for it are, but I'm sure it won't hurt to wait until they've had time to work out some of the other bugs associated with it.
Still, the crash was due to an unhandled exception, which EVGA might want to fix so that Precision X1 no longer crashes as a result.  The crash dump I provided should help with that.  I'll keep that link active for some time.
Thanks all!

 
 

I tried MSI Afterburner with this very update and it seems to be working. So I stopped using PX1 in the meantime, only managing my RGBs.

MSI AB recognized my OC and curve so I said why not. Additionally I can install the security update without any problem.

EVGA should comment on this though.

I tried everything, the only way I got it working was by downloading the steam version.

Same thing, no way to use it but I don't like to use the steam version

Hey, guys just wanted to put in that updating Rivatuner statistics server fixed the issue for me as it was stopping X1 from even opening past the logo. 
 
At the moment though I can't seem to get X1 to launch on startup regardless of ticking it over and over.

That is weird indeed ! I use RTSS all the time so that sucks.. I am using the steam version for now untill the issue is fixed

Is there any news? I haven't updated windows for a while , was wondering if it was ok to do it now
