Clean Install recommended after upgrade from clean windows 8.1 pro installation?

[Hard_ware]

I have a new rig and made a clean install with Win 8.1 Pro.
After that I directly upgraded to Win 10 Pro within running system.

Are there any advantages to do now a clean Windows 10 installation?

Thanks for advice.

One advantage I can think of is that some people have been running into driver issues so if you clean install and find drivers from the manufacture's website then you may be able to avoid those problems.
Personally everything has been running smoothly for me on two computers so I haven't felt the need to clean install.
One thing you might try if you haven't already is do a disk cleanup which will delete your Windows 8 files and some other stuff. If your not going back then might as well save an extra ~20Gbs.

I have upgraded 4 systems and the only issue I had was , I downloaded thew more recent graphic drivers from the sites , otherwise very smooth process.

Probably not. But then again the main issue with doing a clean install is wiping the drive of any files or programs already installed but since you're already clean there is no harm in just taking that extra hour to do it.

For the upgrade within the running Win 8.1 System only 3GB were downloaded whereas a clean install from USB Stick needs around 6GB.
Does that mean an upgrade within the running system - as in my case described above - ends up with different operating files or drivers etc?
If yes I will consider a new clean install otherwise I just leave it as it is now.
