The process "Delivery Optimization" seems to be taking up my entire bandwidth.

Under Windows Update Advanced Options I unchecked "Allow downloads from other devices", and I just have Windows Update set to optional right now to give me the choice of whether to update... but still Delivery Optimization is taking up my entire bandwidth whether I download the update or not..

I decided to just get the update it wants me to get, hoping that would fix it.

I've been trying to download this:

2024-11 Cumulative Update Preview for Windows 11 Version 24H2 for x64-based Systems (KB5046740

Sadly, it has been stuck at 1 percent for hours and hours.

Any help would be greatly appreciated! Thank you.
 
Where is Update Previews? Is that within Windows?

The instructions on how to disable Update Previews when I googled it didn't seem accurate, there is no "Updates and Security", and within "Windows Insider" there is no option to disable previews, so I'm lost.

Strangely, I stopped what it was downloading in the App Store and it is still tying up bandwidth a few days later, can't figure out what it is suddenly downloading.

I believe you may need to check your settings to see if you are also uploading update content, effectively doing your part to "optimize delivery" of updates to other devices, as I have understood this to mean.
But I'm not a professional, and I didn't Google it, so there's that disclaimer. :laughing:

Go to Windows Update > Advanced Options and scroll down to Additional Options, where you will find Delivery Optimization.
Scroll to the bottom of the page to the activity monitor section.
This displays details about download and upload usage.
Look for Upload Statistics. Could this be your issue?

If so...
In Delivery Optimization, expand the first section that allows downloads from other devices.
Read carefully. Turning it on automatically means you are also uploading data to other devices. Or, in Microsoft's words, "your device may send parts of previously downloaded..."

You can have this on without also uploading much data. It's just an extra step.

Scroll down to Upload Options and expand that section.
There is an option to limit bandwidth (and above it for downloads too, of course).
It can be set to 5%.
Check your monthly upload limit. That number can be as low as 5 also.
Or you could turn Delivery Optimization off. My personal choice has been to leave it on, as it's worth that small percentage of data.

Hope this helps.
