Hi Guys,
Since ma update to Nvidia driver 591.74 and I guess windows update just few days before, i can't get off this hard crash on Windows 11..
I get back to some previous Nvidia version and even if It seems to be less frequent, i still get hard crashs..

Any hint about windows tweek maybe, would be helpfull.

Thank you.

i had the same problem. I rolled back to 581.57 just after use DDU to clean unstall 59x.x version.
It work fine now.
cheers,
F.

Hi Ebenfred,
I will give a try, thank you

Do you get thread exception error? I started to get it last week, not sure if related. I have to restart the computer each time.

Hi @heileif,
Do you mean in Houdini log or in windows log?
I will take a look if I get something similar

Rolling back seems to be the official way, see this announcement thread for reference:

Hi Protozoan,
saw it this week, my rollback didn't resolve the issues.. I expect something in Windows 11 update's side..

Windows error. Suppose I have a different issue then :/

Hi Heileif,
if you're on Win11 with and you get the update on 14th jan 2026, it could be related too..

I have removed the 14th jan update, and rollback on the Nvidia driver. Been stable for around 1 hour now of rendering

You're luckier than me
Windows can't let me get back before 14th.. It has no save point..

I removed if from the Windows Update window.

Windows Update>Update history>Uninstall updates.

I removed the windows update and now is no longer crashing. Also paused the updates, but how am I suppose to manage this? Just dont update windows? That's not safe I guess. How are you guys handling this? Thank you.

I desinstalled the january windows update and all is fine too. I guess Microsoft will come back with a fix because this did a lot of noise in the web...

Wait and see.
