Windows 10 update 1709 slows computer to a halt

I have a 2 month old Dell Inspiron 15 with Windows 10 Home edition installed, no additional apps and virtually no other files on it (yet). Unlike previous versions of Windows, it seems that Win10 "forces" the installation of updates. Today it began downloading and installing updates including what seems to be a very major "rebuild" of the OS. My system has Win10 build 1703, and the update is to install build 1709.

Downloading this update took about 2 hours. Then when it started to install my computer slowed to a crawl and became almost totally unresponsive. Task Manager showed the write-to-disk was maxed out at 100%. This lasted for another hour or more.

Eventually Windows Update said that this update had failed to install. I closed down, and when I rebooted it said "trying again" and then after some time, that a restart was necessary.

I restarted. The system startup was very slow, and once going, the computer seemed very slow. Task Manager says that (with no other apps running) the disk is still maxed at 100%. I deduce that the updater is still trying to install that 1709 update.

A quick search of online forums reveals that this seems to be a widespread problem. Lots of people are asking how to block or prevent this 1709 update (apparently in Pro and Business versions of Win10 it can be delayed, but Home edition users have no choice).

In despair I decided to do a System Restore. As I write this (on another - Linux - computer), the Win10 machine shows a blue screen which for an hour has shown the words .... "Please wait while your system files and settings are being restored". I rather suspect this isn't happening, but I don't yet want to do a hard shutdown.

Even if System Restore completes (and that's a big if), I suspect I will still be faced with the problem that the 1709 update will keep trying to install, and will cause the system to slow to a halt.

What can I do? My personal preference would be to bin Win10 totally and install a Linux OS. But this laptop is used by several other colleagues who aren't familiar with Linux and want to cling to Windows.

Quick follow up. System Restore did complete. But as I feared, the computer is snail-like, and Task Manager shows the disk usage at 100%. CPU running at between 5% and 15%. Hard to tell what specific processes are hogging the resources, as most show 0% apart from svchost and System.

If it is that pesky and persistent updater trying to write to disk, how can I stop or disable it given that (I assume) the 1709 build-update files have been downloaded and the updater is repeatedly trying to install it?

You could download Process Explorer from click here which will show you what is hogging your resources.

As your laptop is only a couple of months old, I would advise you, without any delay or hesitation, to contact Dell support and they will be able to advise you in a much better way than anyone can from a forum, good as this forum is. They are the experts in relation to your laptop

Dell support is what you pay your money for!!! In my experience, they are very helpful and happy to assist you

Have done some further research. The problem isn't with Dell. The evidence points clearly to the culprit being Windows 10 update 1709 (which is massive, almost like a complete reinstall). I've followed the advice on this excellent forum site [here]. This suggests disable AV program, delete Software Updates folder to get rid of possibly corrupt or incomplete update, and disable Windows Update so it doesn't try to download 1709 again. Did that, rebooted, and my new Dell laptop absolutely flies into action - no lag, CPU and RAM not burdened at all, and no write/read load on the disk drive.

Proves what I had suspected and what many other online posts confirm: this new approach by Microsoft,forcing major updates automatically in Win 10 has the potential to seriously foul things up. If and when I do decide to install the 1709 update, I plan to do so by separate download from the Windows Update site.

Follow up post - again. I see that the link I posted hasn't appeared correctly. It was to the wintips.org site. Why is there no option to edit posts in this forum in order to make corrections?

1709 is the Autumn or Fall upgrade/ that you will need to keep Windows updating. Older versions are defunct so it is important to keep up to date on these versions. More important now than has ever been.

Uninstall your security suit (disabling is not enough) via their removal tool but keep a note of your subscription key for re-installing as things have changed registry wise. Defender will kick in. Make sure Windows Update is enabled and only Defender is showing in 'Security and Maintenance' via control panel.

Now check for updates and install the FCU. Once on the desktop let it settle for half an hour or so. Check task manager to see the CPU/Ram/Hard drive usage. It should settle down before then though. Try using it for a while before re-installing your security suite you had before.

Your issue might be something to do with this and it does affect AMD to a lesser extent from what I gathered.
