Bios update?

[Jebencun]

Hello to all nice people here..this is my first post! hope you can help me.

Im running Asus Z170 pro gaming motherboard, i had i5 6600K and now i bought i7 7700k.(which is the best cpu that this motherboard can take)
Butttt i need a bios update "so that the processor can unlock its full potential".. my latest bios is "3016" and there is 8 bios updates that came out since this one that im running

After i put my new cpu in and turned on the pc it booted normaly and im still on my old windows, it even sees that i have i7 7700K running when i check "my computer>properties"
also a guy in a shop told me updateing bios is dangerous and i might lose my motherboard if i do it wrong, he seid that i need to update everly single update one by one until i get to the newest one (i cant directly download latest one and update it).
So my question is.. is it true that i need to go through every bios update one by one and how come that my windows are working properly and system detects that i have i7?

i seen on forums that people are saying i need old cpu to update bios and that wins should not work on new cpu

 

can you tell me a litlle bit more about it because im thinking of doing this by myslef, the guy at the shop is asking for too much money..

Make sure you understand the possible risks that a Bios Update can have before continue.

Its still brand new one.. i have 2 screens running and one is 1440p

Can that be the reason?

 

Also.. about the update, why did the guy in the shop told me that?

And should i be good?

Just put latest updates from asus page on fat32 formated removable drive and run it from the bios menu

And make sure i dont lose eletricity meanwhile

Is it that easy?

 

EDIT:

I just checked that my bios supports new gen of cpus

Take a look at this, the red one is the one im running right now

Thing is everything seems to work fine (except your 1060) so you probably don't need a bios update, so why risk it?
