Windows 7 Clients have high memory usage due to Windows Update

In the process of Migrating from SBS 2003 to a W2012R2 Essentials server.
I have migrated the data and uses and the major thing left is migrating the users re0directed folders.

However just after I have gotten all of the computers joined to the new server, and I have removed all but the Redirected folders GPO, The Windows update on all of the clients computers (Windows 7) have gone crazy and take large amounts of memory (over 1Gb in some cases.)

Any ideas or suggestions.

On the W2012 server I have set the updates to be dome via the Microsoft site, not a local WSUS server.

Do you mean that when users are running windows update that updating takes 1GB of RAM memory or are you saying the downloaded files for windows updates is take 1GB or more of disk space? If you are referring to files on your local drive then 1GB is not all that big. Here is a link to explain why and how to remove some of those files
Windows Update using a lot of RAM has been a known issue for a few months. MS just released a hotfix for it this month:

Apply the hotfix and see if RAM usage drops. I had a similar issue on one Windows 7 PC at work, and this fixed it.
