Windows 10 updates can be complex for users with slow network connections or limited bandwidth. Windows 10 recommends staying connected to the Internet at all times during daily use, and both updates and the Microsoft Store consume your Internet data.
Slow network connectivity has created a variety of drawbacks, and Microsoft introduced the Deliver Optimization feature to allow users to limit updates as a percentage and use bandwidth in the Microsoft Marketplace. In the Windows 10 May 2020 feature update, Microsoft allows users to set the absolute value of bandwidth.
The new transport optimization options will give you more control over your network connection, giving you control over how Windows Update and Windows Store should use your Internet connection to download updates. In Windows 10 Version 2004, you can set an absolute bandwidth limit to ensure that Windows Update, Microsoft Store, and Microsoft products don’t consume your Internet connection because of their background downloads.
If you set an absolute value for bandwidth usage, Windows Update does not attempt to use all of your bandwidth/network connection speeds. Instead, it will try to dynamically optimize the amount of bandwidth it requires, and Windows Update/Microsoft Store usage will not exceed the value you set. This new transport optimization setting also applies to app updates and other Microsoft product updates in the Store.
