I was having a similar problem, and after multiple attempts (over 7 times) trying different solutions like disabling virus protection, disabling startup programs, running update database corruption repair, etc. My computer never got past 81% before freezing
and not updating.
I stumbled across a forum talking about problems with Anatel PCI-E Wlan cards (wi-fi) and old drivers that would hang up their computers and after removing the card (not just disabling) their machines would update and run fine. Since I was running my machine
through an Ethernet connection, connected to an access point, I could remove the Anatel card in my computer and still have an internet connection. I tried it, and my computer a Gateway FX6860 updated to Windows 10 Fall Creators version without any problems.
Check to see if you have an Anatel wifi card and remove it and replace it with something newer or an Ethernet or usb connection to the internet and try the update. this worked for me.
I've been having the same problem with Creators Update (continuous crashes and blank screens between 75-81%.) I tried every solution shown here (especially now that MS is force-feeding this update down my throat and is now constantly trying to update from
1607 to 1709) then I stumbled across your post. I never paid any attention to the fact this PC did in fact have a PCI-e Wifi card plugged into it, as I never used it (This PC is hardwired with an Ethernet cable.) So after my 5th crashed update since yesterday,
I stumble across this post, pop the lid off my PC, pull that Wifi card out and lo and behold find out it's an Anatel (device manager never identified the card as such--it called it something from Ralink Technology and could not find anything that co-related
the two companies.)
Windows is trying (again) to shove this update down my throat. But this time without that wifi card. If this works, I shall give you internet hugs * infinity.
UPDATE: SUCCESS!! A billion thank yous for sharing your solution. I now am running 1709 and would never have connected the update failures to this WLAN card and its failed drivers.
