So, after windows update some cards just did not want to work...

The soultion is actually quite simple.

1. Reinstall / patch first blockchain drivers (if for some reason m$ decided to replace your drives as well)
HowTo here:    • [SW: How To] - Get 28-29+ MHs (when stuck ...  
2. Change the swap file size to 32GB (if that does not work then to 40... etc... untill it starts to work propertly)
3. Profit??? :)
I assume this is not the issue if you have 16GB of ram (or maybe 12) however, with 8GB it does seems to be a problem.
*** IMPORTANT: You need to have the latest version of miner!!!

*** if you have nVidia cards and you still have issues with dag creation try adding: "-eres 0" to your batch file

Hope this video helps in some way, if you have any questions, don't hesitate to ask.
