N7110 BIOS upgrade (Windows 10)

After upgrade from Win7 to Win10 I have noticed that Microsoft has installed Dell BIOS version A09 to my computer. I don't believe this BIOS version was originally on my computer before upgrade? Dell recommends to use version A06 or A13 for Win7/8. So far I don't see any problems running A09. Should I leave this version so as it is or should I upgrade it to A13? Thank you!
