OK I see now, did you perform the initial upgrade?
If so, you now likely now why the majority are buggy at best, and at worst, one may have a lot of BSOD's. This is because by default, during the upgrade, Microsoft upgrades the original drivers with generic ones as part of the upgrade process. Usually (unless a totally botched upgrade), installing the newer, proper drivers fixes things, beginning with the chipset driver. Microsoft users whatever Intel or AMD drivers are available, not those customized for one's computer & may have required special features for things to run smoothly.
One last tip on these machines, and don't worry, UEFI is simply the replacement for the 'BIOS', just as it replaced another technology 12-15 years earlier. That's simply technology evolving. Come another 12-15 years, there'll be a replacement for UEFI. Other than the name change, just run as one would normally run a computer. Though one thing needs to be disabled to prevent excessive wear & tear (feel across the bezel when 'shut down') & it'll be seen that it's not, often still quite warm. This is also an expensive battery killer, those for newer computers cannot be purchased refurbished for $20 or less on eBay. More like $100 & up, and some makes/models may reject rebuilt units that often has inferior cells compared to the original. If it were meant for computers to Sleep all the time, there would have been no 'Shutdown' option for years prior to Windows 8's release. Computers, like any other device, needs rest that can be achieved only by a full Shutdown, not a 'hybrid' one.
It's all in the Power Settings to disable Fast Boot (link below), a gimmick to make users think that their computers 'boots' faster, when in fact, it's simply being awakened.
May as well also disable Hibernation, which should also in itself disable Fast Boot, though have always done the above before the second, so can't say for sure. Simply right click the Start Button (or type it in the Charms bar) & choose Command Prompt (Admin), will have to right click for Admin option from Charms Bar results & when the screen comes up, type in (copy/paste may not work if not exactly lined up) & press Enter:
powercfg.exe /hibernate off
Source, and the first paragraph (a warning), tells us why to disable Fast Boot before Hibernation, though if one desires, can leave Hibernation alone. Problem is it requires so much drive space, and if running a SSD. neither Hibernation nor System Restore are recommended to use. Use regular Sleep instead, this stores data in the RAM, where it belongs, the fastest storage one can have on our computers, hundreds of times as much with a regular HDD & 50x faster than most consumer oriented SSD's.
Another tip, how to bring back the old fashioned way of entering Safe Mode (the 'F8' way) & how to reverse, the article speaks for itself (works for W10 also).
There's lots more other tips, though have covered the more practical ones above. Should you install a SSD, you'll need to downsize the pagefile, if a Samsung, the 'tuning' software will do this for you as long as 'Maximum Performance' isn't chosen. Maximum Reliability or Capacity are the better power options that writes less data to disk, making it last much longer. In addition to automatically reducing the pagefile to a minimum of 200MB & max of 1024MB, and most anyone with SSD experience knows that a power plan with Hibernation is downright destructive to the drive (it's a huge write every time used), shaving years of life away for little to no visible gain. Using one of the others & Sleep as needed are all that one needs to do with a Samsung SSD, the most popular brand on the planet.
Though stay as far away from the 750 EVO's as possible, for just a few more bucks, can get a 850 EVO with a 2 year longer warranty & longer lifespan (measured in TBW).
