A way to stop background network usage


Hi all!

I always update my system before anything to minimize anything that could interrupt my activities. I recently had a problem with Windows Store Apps not updating. The problem was very persistent and I decided to refresh Windows. Now Apps Updates and Store are working just fine and everything is up to date but from time to time a service called "Microsoft upload/download host" comes up and start using lot of bandwidth. My internet speed and latency are very basic so I can't afford to have any interrupt. I wonder if you guys know a way to stop or delay whatever this service is doing until I decide there would be no need to use internet.

Any help will be appreciated! I'm very happy everything is working back just need this last thing. Thank you

Hi, could be related to this:


and try disabling tips about Windows:

Thank you for answer!
I have disabled those items. Also, "apps that can run in background". In the previous Windows Install I disabled "Content delivery manager" to try but wasn't related to it. I read Windows Spotlight could use the service to download lockscreen images. I'm not sure to be honest because the time it use my internet for a couple of minutes.
What else can be downloaded (or maybe uploaded ) through this service ?

Hello, you should be able to achieve this (0 Network activity when idle) with very little effort indeed, unless sthg is wrong or you do have some legitimate activity:


Note the number of (small) startups I have and processes running. Despite that, quiet.

If you are experiencing unexpected network activity, please post a screenshot of your task manager clearly showing it and the related process.

Well, nothing came up with network problems so I guess I'll keep watching until service start again and then check Perfmon. In the other hand. after refreshed my computer to resolve Store Apps not downloading / updating the issue is back with same symptom but different error code ( 0xc0ea000a ) . So... I guess it's a Anniversary update related problem. I discovered a lot of people posting about it and a lot of help too. Some people were able to fix it some others like me.. well
Ok so what is the procedure now? Should I mark as solved or you close topic or leave it open.

Again, thank you for your time!

Hi, you're welcome to leave it open for a bit- only you can close the thread and mark solved.

Finally ! I installed Process Hacker and the service started today. I was able to suspend it to check its properties. And I was wrong with my previous statement. It actually points to Windows Spotlight folder:

Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy

and it's announced as Content Delivery Manager. I can't believe the first time I stopped this last services it was still downloading something but maybe it was my imagination.
Now that the mystery is solved I need a bit more of help. I wonder if you could help me find how does Windows actually start this service. I have searched through Scheduled Task but I don't see anything pointing to this So, any idea how can I achieve that goal? Thanks
By the way also I'm a bit surprised it takes plenty of time to download just a wallpaper. My internet don't suck that much. Maybe it's getting some other stuff.
