How can I throttle the bandwidth consumed by Windows Automatic Updates?

We have many Windows XP computers sharing one connection to the internet. These machines are set to download all available automatic updates and then prompt the user to install them.

Whenever Patch Tuesday rolls around, our internet usage pegs out, and remains that way for most of the day, and sometimes into the following Wednesday. This hurts!

I still want the machines to start to download the updates as soon as they are available, but if it takes until Thursday or Friday before the last updates are downloaded, that's still better than the latency and dropped connections we are seeing now as a result of the internet connection bottleneck.

What can I do to throttle back how rapidly each machine downloads the updates, while still having them all start the download process as soon as the updates are available? I have no desire to run a WSUS server. Also, the internet connection is more than enough, whenever there are no updates to download.

Solution 1:

Traffic Shaper XP is a perfect fit.

Features:

• Speed limiting for bandwidth-intensive applications and protocols
• Flexible address and port filtering
• Acknowledgement prioritization to speed up congested links
• Real-time traffic monitoring and stream statistics

Traffic Shaper XP is freeware

Solution 2:

Seems like you should really consider installing a WSUS server. Then only one machine downloads the updates -- all the clients go to it. Free and reasonably easy to setup. All the machines don't need to be in a domain, either (although that certainly simplifies setup).

In the meantime, you can also look at throttling BITS via this Technet article.

Solution 3:

Its a bit of an ugly hack but i tend to use this Offline update on a network share as a poor man's WSUS server, especially for getting fresh installs up to speed. Tie that in with a sceduled task, and turn off automatic updates, and it should do
