I caved and reinstalled windows 10 preview. Been using it for about an hour now and haven't had any issues. Haven't done anything to system intensive, upon my initial install I was having excessive fan use but as soon as I disabled Diagnostic Tracking Services the fan went silent instantly. Someone did mention turning of IP Helper might help as well for anyone having issues.
Now that I got that out of the way I was first using the Technical preview a few months after the initial release, I would definitely have to say it has come a long way since. I do see improvements in the GUI all around, can't say much about speed just yet but the system seems stable.
I will make sure to update any glitches or quick fixes I find on my way hopefully I will stick with this until the official release this time.
