Didn't even think of the little pop up box! I will look into disabling it in the group strategy. That is what is likely causing it not to be able to be closed from AM.
The rules/trigger is quite comprehensive, especially when combined with custom scripts in batch or C# but didn't think of the window. Thank you so much!
(I don't have the exact translation, it's not in english here)
It's in group strategy: administration models, windows error reports, do not display the user interface for critical errors... set it to ENABLED
For Win7 I think it's all. For Win10 there is another one at the same place. If you can't find it I'll do.
I have found where to do it, once I get home I will apply this. Thank you!
