Win 10 Bootcamp won't boot after forced Windows Update

My Bootcamp partition of Windows 10 won't boot up after Windows Update installs the latest Windows OS (v1709). It gets to the blue startup screen, then keeps cycling itself of and restarting.

This problem has been recurring since Windows 10 updated to v1709 last Fall. It seems to be an issue caused by windows update. I can downgrade to 1703 and it works fine for a while, then upgrades and subsequently refuses to boot. What I do now is, on the Mac OS side, make a full clone of my Widows install using Winclone. Then when Windows fails to boot, I restore Windows from the backup. It will work for a few reboots until windows update mucks it up again. I've tried everything to prevent it from updating, even calling windows tech support and having them disable the v1709 update, and manually turning off Windows update, but without fail it turns itself back on, updates, and then fails to boot. I suspect it's related to a Bootcamp driver not being compatible with the latest Windows 10 version.

I've called Apple about it but they fail to acknowledge the problem. Microsoft wasn't much help either.

I'm on the latest 2017 27" iMac running High Sierra, so it's not an issue about running Win 10 on older hardware.

iMac with Retina 5K display, macOS High Sierra (10.13.3), Bootcamp running Windows 10 v1709

I would like to take the opportunity to give you a big "Thank You"!

First of alle I installed the group editor and changed the settings for updates. This saves me the money for Windows 10 Pro license.

Second I took your advice to download the drivers from bootcamp.com. They make a big difference for the Oculus Rift. The game Fallout 4 was unplayable before, very jerky even with lowest settings. Now all goes smooth and I changed nothing other than install those graphic drivers.

I do backups with winclone and keep always the last two.

Restore Points do not help me. Yes I create them frequently, but if Windows come to its endless boot loop it will not accept any restore points. This was the basic problem Shirley outlined at the beginning of the thread.

It is very strange. If this happens I can do nothing any more. Repair and Restore do not work and also with a repair DVD or bootstick can do nothing. So in this case all otherwise valid options fail.

I would be glad if you just somewhere here will give a short statement when you think this problem is solved. So long I try to let all updates deactivated, what works well so far.

Definitely, I can post a message on this discussion.

With potential new security issues being discovered very frequently, this is risky. As long as you are aware of your public connections and monitor them well or do not connect from Windows to any public networks, it may not be an issue.

As I wrote before each time I had to install W10 anew it is less than before that I do on the windows side of my system.

In fact its only games (most on Steam) and the games from Oculus Rift glasses that remain on the windows partition. I hope one day apple supports games better, then I can delete windows entirely.

I do not even us internet on windows. Just play games and close it. So I guess I can live some time without updates. Maybe after some months I just give it a try and if it fails I can restore with winclone.
