Hello, i had constant problem with Irfanview 4.50 version x64 on my windows 10. It kept resetting file associations and not accepting ur program to be used as main image opening tool. Windows kept informing me that irfanview "created problems" in a announce. I've solved problem by installing x86 version.
dxdiag (only part as i could not paste whole thing here):
