Should I reinstall windows after upgrading mobo/cpu/gpu?

So a few days ago I upgraded from a H81M-DS2 mobo, i3-4160 and gtx 750 ti to Asrock Z370 extreme4 mobo, i5-8600k cpu and gtx 1080. I kept my old hard drives, both with windows 8.1 pro on them installed. So once i selected the boot device it started windows, said "checking devices" and then I signed in and got to the desktop. The network adapter driver and some other drivers weren't installed so I went to the mobo's website and downloaded the Intel Lan driver ver:22.10 and INF driver ver:10.1.1.45 from another pc of course. Put them on flash and installed them on the PC needing the drivers. Once i restarted, everything seemed fine in device manager with no errors and I had internet connection.

Haven't experienced any problems so far but I was expecting having to reinstall windows because that seemed to be the result for a lot of people. So my question is, should i still reinstall windows to fix some potential problems that might occur? or was the driver issues the only real problem with not reinstalling?

As a general rule, windows installation from scratch is mostly required when performing platform change from intel to amd and vice versa, or when doing a large generational jump between chipsets (i.e. from intel G41 chipset to Z270). You did neither; only a few drivers were required as you were able to see. And as long as you don't experience any issues, there is no need to install from scratch.

Decent, thank you
