Yesterday I found my C: drive had suddenly filled up due to 80 GB appearing in C:\Window\TEMP. There were three types of files and about 13,000 of each of them.

AppXDeploymentServer_B1874DF3-7BCE-0006-9D58-88B1CE7BD401
AppxErrorReport_B1874DF3-7BCE-0007-FF72-88B1CE7BD401.txt
AppXPackaging_B1874DF3-7BCE-0007-FF72-88B1CE7BD401.evtx

Possibly connected with last night's WU to 1803 (OS Build 17134.407).

I deleted all of the files and they stopped.

But as I feared, after a reboot this morning they are being downloaded again at a rate of every second or so.

In Services I found AppX Deployment Service (AppXSVC):
"Provides infrastructure support for deploying Store applications. This service is started on demand and if disabled Store applications will not be deployed to the system, and may not function properly."

It is enabled and set to Manual. But it cannot be stopped or disabled, at least without deleting some of its upstream dependencies, which I'm not going to attempt:

Does anyone have any suggestions on how to fix the issue without major side effects please?

Anyone else seeing similar behaviour please?

Open Settings.
Click on Privacy.
Click on Background apps.
On the "Background apps" page use one of the two options:

Turn off the Let apps run in the background toggle switch to disable all apps acquired from the Store.

Because disabling ALL apps from running in the background would cause some preferred applications to stop running. Instead, it would be better to turn off unneeded apps individually. And that should also prevent the temp files from building up.

And I have noticed on some Windows 10 computers, they tend to ignore those particular settings anyway. The applications will still run. It doesn't work perfect for all.

Hope this helps.

Thanks Garyw. Can't be 100% sure but I reckon that of the various steps I took that was the one that fixed it.

I disabled about 90% of the apps there, i.e. those I don't use or anticipate using.

Of course, another reboot might re-trigger the issue...

I don't know what is going on but I found a thread where an repair install was suggested and it worked.

If you have some reason for waiting so long to upgrade, other than just being cautious, please advise.
Not sure what you mean Saltgrass? I'm right up to date according to Settings > Windows Update.

Seems fixed - see my reply to Garyw.
