Is there a way I can selectively make some optional Windows updates permanent? In particular I'm looking to make the definition updates for Microsoft Security Essentials permanent.

I'm using Windows 7 Professional 64 bit.

This article could help : Microsoft Security Essentials Automatic Virus Signature Updates.

The article describes how one can use the build-in Windows Task Scheduler to check for Microsoft Security Essentials Signature Updates on daily, weekly, or monthly basis, without requiring the scheduling of a scan.

Happy this worked. FYI it is not enough to accept - the bounty has to be manually awarded. – harrymc Dec 28 '10 at 8:04
Here is a link to a way to change the frequency of MSE updates. The default is every 24 hours.… – RSMoser Jan 14 '11 at 19:03

If you have it check for updates prior to scanning, and scan at least once a day, that's a sort of automation. Otherwise I think you would have to run a script of some sort to scan the names of available optional updates and install anything with Security Essentials in the name. Microsoft doesn't make a method available to do that.

No you can not set the MSE updtaes as required or permanent. Setting the MSE updates as required or important could make it seem that MSE is a required installation for Windows. This would then lead to some legal issues. See this article from Computer World

If you set up a scheduled scan, MSE will download the updates before it starts the scan.

To set a scheduled scan open up MSE and click on the settings tab. Check the box "Run a scheduled scan" and set the day, time, and type of scan. Then make sure the box for "Check for the latest virus & spyware definitions before running a scheduled scan" is checked.
