Attention IT managers of small and mid-sized businesses:
With the release of the Microsoft Windows 10 operating system on July 29th, 2015 Microsoft increased the amount of bandwidth available for Windows Update downloads. While this change makes sense, our testing to determine how much bandwidth is actually consumed indicates speeds of 50Mbps or greater. We are noticing this change is causing internet bandwidth issues when our employees download Windows Updates to their machine directly from Microsoft servers. This means the Windows Update downloads starve the rest of the machines on our network from accessing the internet. With Microsoft’s Patch Tuesday coming up next week this change could cause bandwidth concerns for some small to medium sized businesses. Currently we have found two possible solutions for your IT department to address the internet bandwidth matter: 1) One way is to limit the network speed of Windows Update downloads to 25% of your internet bandwidth. You would be able to accomplish this by setting up an internet traffic shaper (usually part of your network firewall device) which limits the download speed for the following servers: · http://windowsupdate.microsoft.com · http://*.windowsupdate.microsoft.com · https://*.windowsupdate.microsoft.com · http://*.update.microsoft.com · https://*.update.microsoft.com · http://*.windowsupdate.com · http://download.windowsupdate.com · http://download.microsoft.com · http://*.download.windowsupdate.com · http://wustat.windows.com · http://ntservicepack.microsoft.com 2) The second option is to set up a Windows Server Update Services (WSUS) machine on your network. The purpose of this machines is to download all of the Windows Updates once to a local machine. Then direct the other machines on your network to download the Windows Updates from the WSUS machine instead. The following Microsoft TechNet article shows how to setup and implement this on your network: https://technet.microsoft.com/en-us/library/Hh852340.aspx
