Hi - hmm. I'm assuming you've tried rebooting?
If that doesn't/didn't help, could you:
1) Run the game in administrator mode, and
2) Run the game in compatibility mode for Windows 95?
If *that* doesn't work,
this thread is talking about a different issue - and in fact possibly a different OS version (if you've got windows 10, anyway), but the potential solution there seems like it may be worth a shot.
Also: do you have something like MSI Afterburner or similar running? That's known to cause problems similar to what you've got. Also, possibly worth a shot: killing (via task manager) and GeForce experience executables.
And, finally, if none of the above makes a difference, you might try downgrading the graphics drivers to their previous version...
(Also: how certain are you that the windows update/geforce update is what broke it? E.G. is it possible that something else was installed/updated on the system in the same timeframe? I mean, what you're saying is a reasonable surmise, but I just want to make sure we're not excluding anything else - that is, any other changes to your system in the meantime - that might also potentially be the issue.)
