No specific Bitcoin Bounty has been announced by author. Still, anyone could send Bitcoin Tips to those who provide a good answer.

After Windows upgrade from 8.1 to 10 and a few days of used I was found blue screen with next error: DRIVER_IRQL_NOT_LESS_OR_EQUAL (epfwwfp.sys). What is it?

Hi kwidoo, I've edited your question a bit just to make sure that markdown does not eat the "underscore" symbols in the error code above. I just used the </> button in the markdown editor. Also, please post your answer once you find it - I'll be glad to send some bitcoins your way! Thank you, Alex

After some time I found a solution.

This error you can get, if upgrade system with installed ESET software (for example NOD32 antivirus).

You must delete this driver and reinstall ESET software after reboot.

You can use command prompt in the safe mode:

DEL /F /S /Q /A "C:\Windows\System32\drivers\epfwwfp.sys"
