Windows – TEMP folder filling up with AppX files and canot be stopped

windows 10

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.


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?

  • You can disable the broken Windows Store service by hacking it to Disabled.



    Yes run as Administrator

    Navigate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\AppXSvc

    Double-click the Start key inside it

    Change the value to a 4 (which means Disabled for Services)


    When I disabled this, AppXSvc was dumping 1gb of files to my disk every hour, running me out of disk every few days.
