Anyone else experince this over the past 12 hours ? I have multiple machines that errored out on multiple WUs consecutively.

Looking at the logs - most have failed multiple times before I hit them.

A few items to note -

Windows appears only to be affected, my Linux nodes are humming along - not conclusive as if a batch of bad ones may not have hit those hosts yet.

Anyone else experince this over the past 12 hours ? I have multiple machines that errored out on multiple WUs consecutively.

I've experienced the same on one of my Windows 10 PCs. The source of this error is that the latest NVidia driver (388.13) has been released through Windows update, and it will update your GPU driver without stopping BOINC GPU tasks first.
There are two workarounds:
1. Update the drivers manually before it rolls out on Windows update (the tricky part is that not all NVidia driver versions get rolled out on Windows update, and I don't have a source to tell which version actually does)
2. Disable Windows update to update drivers. Here's how. The drawback of this method is that it will stop all driver updates, not just the NVidia drivers.

Thank You Zoltan !

That explains it.

Kind Regards

This method supposedly blocks only your GPU from automatic Windows updates, but I have not tried it.

Well, there are 5 methods in the blog post you've linked.
1. Hiding a driver update is irrelevant regarding this issue, as you can use it after an automatic driver update happened.
2. Disabling Windows update completely to avoid driver updates makes your OS vulnerable, so this is forbidden.
3. Blocking driver installation for a particular device ID (through group policy) is good, but it will prevent you to update the driver manually without first removing the blocking group policy object (then you should disable the given device ID again). This method is linked in the post I've linked.
4. This method is the same I've posted.
5. The Windows update preferences does not have the option of driver updates in the latest release (Creators Fall Update, v1709), it has been removed from the system properties dialog box also.

Darn, this happened to me and I didn't see it until it was way too late.

Is there any way to update the application to make it automatically pause during the update process? I assume this is happening at least once per user per update.
