[Bug]: Windows Update and Store cannot download any files (error 0x80004002, 0x800704c6)

[GhostScript0r]

Description

After running the customized script to disable data collection (exact combination no longer remembered), Windows Update and Microsoft Store are both no longer able to download update.

Windows Update can still search and find updates, but downloading will immediately fail with error 0x80004002. Similarily, downloading anything in Microsoft Store will return error 0x800704C6 - you are not online.

The problem presists even after I run the script to revert everything, and replacing the hosts file with a unmodified clean one.

Pinging windowsupdate.microsoft.com or eedir.update.msft.com.trafficmanager.net [20.72.235.82] is still blocked (100% loss of package).

How can the bug be recreated?

For Windows Update:

1. Go to Windows Update
2. Check for update - new updates can still be found
3. Download update - all update will immediately fail, including Windows Defender Antivirus update, 3rd party driver update, and update of other Microsoft components (SQL etc.)

For Microsoft Store apps update:

1. Go to Microsoft store
2. Download or update an app
3. Get error 0x800704C6 - you are not online

I also had this issue, yesterday. See Discussion post #461 .

I was able to revert the Windows Update Download Error by REVERT of Disable Windows Update data collection. Of the two parts therein, maybe the issue was caused just by "Disable Delivery Optimization Service".

UPDATE: I confirmed that it was just the "Disable Delivery Optimization Service" that broke downloading of Windows Updates for Windows 11 24H2 build 26100.2454. I do not know if the DoSvc can be stopped/started manually without restart.

Two things:

1 - You can't just type "(exact combination no longer remembered)", it's kind of hard to even begin to know what you ran.

2 - Just like @ProgrammerBruce said, you probably just disabled data collection stuff without reading, as Disable "Delivery Optimization" service clearly states:

Caution: Disabling this service affects the functionality of Windows Store. It plays a role not just in Windows Updates but also in Microsoft Store app downloads, especially since Windows 11. There have been reported issues with some app downloads on Windows 10.

[ProgrammerBruce]

An improvement to the script info might be to caution that there are reports of it breaking Windows Updates on Windows 11. The existing wording fails to address this issue. ("plays a role" does not mean "breaks". "Windows 10" is not "Windows 11". "apps" and "Microsoft Store" are not "Windows Updates".)

True, it could have better wording.
