This could be usefull. Anti-CTD guide.

For a long time I've experienced the sudden ctd problem in ETW and NTW, mostly when I was in mid-battle. ^( I've reinstalled everything for some times (playing both games since the release), changed hardware but didn't get rid of this.
Few days ago I've finally found the solution! Here's the instruction:

1. Press start -> open command line with admin rights/(type cmd and press enter)->type there " bcdedit /set nx AlwaysOff " , then press enter. -> Reboot
This step turns off Windows service that allows data execution prevention, it makes other programs not to use memory space not intended for them, mostly by killing them . Microsoft believes that it can protect user from modern viruses, trojans and etc .
If you have same views with MS , then don't do step 1.
2. Turn off sound cashing in game sound options.
3. Turn off vertical synchronisation in game graphics options.

The first step solved 75% of my battle crashes. 2nd solved others. Step 3 helped me with stupid crashes after loadings.

It's guaranteed solution with crash errors like this (at least I believe so):
Problem Event Name: APPCRASH

Some string may differ, but red strings are common and main for these crashes.

Thank you for the info. I had forgotten about it.
