Upgrading Motherboard, Need some help....i3 4170 to i5 7600k

[thereal21]

Hey, Im Still fairly new to the whole PC building thing. I have been using this i3 4170 for a good minute and I figured it is time for an upgrade. So I picked up a i5 7600k which was not compatible with my mobo so I picked up a Gigabyte GA-X150M-PRO ECC to match the socket of the CPU. Soon as I got home after a long drive to the store. I popped the mobo in and set everything in place....and here came the problems. For one the USB 3.0 cable for the front of the case would not reach the slot on the mobo but It didn't really matter to me cause I never used it. But is there some type of way I can extend it ? Then another front usb cord could not reach the slot on the mobo. I have a dell inspiron 3847 case if im not mistaken (Just temporarily). Then here came the biggest problem of them all.... I have 16GB of DDR3 ram and the mother board only support DDR4 so i have to wait to get that as well. But when installing the motherboard, will I need to reinstall windows ? Or can I just uninstall previous drivers and reinstall the new ones ? And what CPU air cooler would be good for a decent OC, I plan on getting the NZXT phantom 410 case btw. Will this case be a good choice for what I am doing ?

(P.S) : I thought I did all my research but apparently I missed a couple of things

First question: What OS is this?
A full reinstall may or may not be required, but which OS it is may make it easier or harder.

OK.
As said, a full reinstall may or may not be needed.
But for the licensing and activation, read and do this before you change any parts:

Then...prepare for if you do have to reinstall.
With all new parts, sometimes the original OS works, sometimes it does not.
Anyone who says "no worries, it always works", simply has not done it enough to see it fail horribly.

Prepare for this.

You will not overclock with an X board, K chips need a Z board. Z170 with a bios update or Z270 straight from the box.

Windows will become deactivated. You might be able to link Windows 10 to a Microsoft account, MS Live, Hotmail, etc with the working I3 4170. Then rebuild the system and use the activation troubleshooter telling it you changed hardware. If that doesn't work, a new Windows license is needed.
