Windows 10 - 2 Issues On Fresh New Install From Usb Pendrive Creators Fall 1709.

Hello. My cpu 8700K
16GD DDR 4 GSKILL XMP ( 3000mhz )

2 disks: SSD Crucial 525 GB MX300, HDD TOSHIBA 500GB 7200RP

I downloaded from microsoft Windows 10 1709 and make bootable iso in Pendrive Kingston Data Traveler. During install i format SSD and HDD. I choose to install Windows 10 to SSD. After installed Windows 10

I faced this issues:

My Windows 10 computer has became slow after cleaned install of Fall Creators. When I load some website in Edge and click on any link, nothing happens and the browser keeps hangs. When I load some website in Edge or Firefox or Chrome ( no matter ) and click on any link, nothing happens and the browser keeps hangs. Next then I open the system settings and click on any setting, the same problem appears.Click and nothing happened. I remember that in this time, windows was installing automatically itself in background nvidia driver. When driver installed that issues gone. And all was fine after 15 minutes.
Also had in eventlogs 2-3 entries:
Windows failed to install the following update 1709

So i tried to reproduce this issues and i format disk again and installed Win 10 again from pendrive. But this time all was fine. And my question is. Why after second format and second clean install Windows 10 i dont had this issue? Thank you for explanation. Cheers From what i read from internet problem is reproducable. I met peoples that they reproduce issue by each fresh install on formatted partition. So why i cant?

Just want to be sure if my hardware is fine. Maybe that was memory related i have XMP profile or that doesnt matter? Otherwise system is stable now, no crashing in games,no errors in memtest86.
