Windows 10: Limit how much bandwidth is used for downloading updates?

    Limit how much bandwidth is used for downloading updates?

    I'm trying to understand exactly how this works in 1709. Here is the Setting Quote:

    The reason is, when I first did a clean install I wanted to make the downloads go as fast as possible, so I set it to 90%, and now am thinking I actually Limited it to 90% from 100% and defeated my attempt at downloading faster?

    If I don't check this Box at all, will I get the Maximum Download Speed?

    If I check the Box and set it to 100% will that use more Bandwidth than the Default Settings with the Box Unchecked?

    Am I making sense at all here lol?

    It is saying it will Limit the Bandwidth so I assume it will only limit and not exceed the Default Settings? Limiting to 30% would be using less bandwidth than 90% right?

    Thanks, FunkMaster

    @dalchina, thanks very much! I could not find that thread myself. I don't know if it answers my question yet but have bookmarked it for another read later. Question still unanswered?

    1. What's Default 30% - 45% - 100% Why don't MS'ers tell us what default is RIGHT IN THE WINDOW? Un-Checking determines Default, but what is default?

    2. Is there any benefit to choosing 100% and walking away from the pc to let it download quicker? Or if one has plenty of bandwidth is 100% going to interfere with normal browsing while downloads are in progress?

    My pc don't even have the "Foreground" choice?

    Checking determines Default, but what is default? - see the tutorial I mentioned- just that paragraph.

    The whole issue only matters if update downloads happen whilst you're working and have a material affect on what you're doing. As I have Pro, and have updates set to Notify, updates and upgrades only download when I let them.

    If your internet is limited in speed, or perhaps shared with others or other devices, then this becomes a useful tool. (Mine's 'only' 38Mb/s)

    Ahh, I'll have to take a second look at my Pro Install also, to see how different it is. I forgot I had a Pro Install on one of my Laptops.

    Actually, I said"
    Un-Checking determines Default, but what is default?
    No, my internet is not limited, luckily I have 30-75Mbps. It always varies by the day or time that I check it. I see, and think this is just not what I think it is, or what it should be?

    I read that link a few times, and it really don't tell me what I want to know, I guess it's assumed by MS that we know Exactly what is going on in the background, so that a somewhat simplistic set of directions will suffice.

    Again, Un-Checking Determines Default as it says in your link, but what is Default? I presume Default is 100%, which equates to the full amount that MS has let Windows 10 use under what ever parameters they have decided. But if I have a super fast connection, it would be nice to allow it to use even more Bandwidth IMO. Some folks where I live have 100-120Mbps, or Gig Speeds, and if so, it would be nice to allow a faster download of Updates. I guess if one has super fast internet speeds the Bandwidth will increase by some pre-configured amount.

    Now, it seems that at least now MS is making the Major Updates take far less time, so this is good. All in all it seems as though my Windows 7 machine Updates quicker.

    Thanks for your help, I think I understand what is going on with it all now. I've never seen that MS makes things clear, and that is the problem for me here. They should note that setting the Bandwidth to 100% is same as default, and if it is not I surely don't get it? And, should point out What Default is? Maybe people want to choose something a little more or less than Default, but I see no mention of Default anywhere accept for Un-checking the Box. Geese, I feel like a Doctor, all these boxes I have to check.

    From the tutorial as noted above:
    By default, we're dynamically optimizing the amount of bandwidth
    your device uses to both download and upload Windows and app
    updates, and other Microsoft products. But you can set a specific
    limit if you're worried about data usage.

    - which I read as 'there's no fixed default' - there's some algorithmic determination of what proportion of available bandwidth is used.

    How to Limit Windows Updates Download Bandwidth on Windows 10
    Activate the “Limit how much bandwidth is used for downloading updates in the background” and drag the slider to set a limit as a percentage of your total available bandwidth.

    As this window notes, Windows Update won’t try to use all your bandwidth by default. Instead, Windows Update tries to “dynamically optimize” the amount of bandwidth it uses. But this option allows you to ensure Windows Update won’t go above a certain percentage of your available bandwidth, no matter what.

    Limit Windows Update Bandwidth in Windows 10

    Windows Update has always used Background Intelligent Transfer Service (BITS) to download updates. BITS uses idle bandwidth to get them, so in theory, if you are actively using your internet for something else, the algorithm for downloading of updates should sense this and back off or lower its bandwidth consumption. However, due to the size and frequency of Windows 10 updates, this does not seem to actually work as well on the latest OS, compared to previous releases of Windows. Many users have been complaining that Windows 10 updates disrupt their online activities too much. The newly added option to control the bandwidth should appease some of these complaints.

    Good stuff dalchina! I really liked that last quote as that is what I've seen working on client pc's. My pc's all seem to work okay, but mine are all Clean installs with no bloatware etc. Always looking for new ways to make this less of a problem. Sometimes when we start working on a computer, it just bogs down, and we're always trying to use some technique to stop this. With Wifi, using the Network Settings, or sometimes even just disabling in Services until we can get some work done.

    Thanks again, this has cleared some things up for me

    I could appreciate in some cases you need to stop the thing repeatedly trying to update and failing. MS has made this harder as you've no doubt found.
