Clarification Request
It's odd they don't show on Disk Cleanup.

everything was fine before the update

this is the path to the folder i found it using TreeSize

I've found rogue apps aplenty over the years

That don't take to Windows updates. OK, that's the right folder. I am very interested in those files that don't show in Disk Cleanup.
How about a few names?

If those files are currently open or locked you might have to use tools like Process Explorer or Handel noted at

-> DID YOU TURN OFF THE UPDATE SHARING? This can cause a lot of Internet and disk use.

They're Probably Microsoft Store App Files

And MS Store will continually attempt to autoupdate the AppX items when it's not working correctly. Read the links below for their discussions and fixes.

This one is an older discussion but a similar issue:

Apparently, any Windows Store apps or any other AppX items you're using will continually cause new files to be placed there. It also places new files and logs if you're using Windows Defender and you use Windows Updates to update it. In your case, because I see error reports as one of the files that is being place in your Temp folder and the same file name appears to shown in the other larger files , there may be a problem with one of the apps. Find which one is throwing all those errors and .tmp files and you can uninstall or disable it. unfortunately, we can't see the full file name listed or we might be able to help identify the app. Or maybe Microsoft will fix it in an upcoming update. Maybe...

Another one of the fixes was to set to disable or manual the "AppX Deployment Service" in "Services" assuming you don't use any applications from the Windows Store but I'm not sure that's a perfect solution since it may break other applications you need..

Hope this helps.

Thank you very much

The files stopped reappearing.
I'm not sure what did it, it was either deleting the xbox app with powershell or disabling AppX Deployment Service.Either way thank you Love

This is the solution.

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.

That's Not Ideal, Specially If Running Windows Defender

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.

Disable the store app

Press winkey. -> type: gpedit.msc ->Allow for changes.

Go to: Computer Configuration->Administrative Templates–>Windows Components->Store
In the right pane double click: Turn off the Store application
Set to enabled and hit Ok

Restart Pc

Go to c:/windows/temp
Delete all files. No new Appx files should be generated (but wait a few secconds to be sure)
