How long do you want the "New Item" flag to show?

I was asked by my customer a few days ago to make the "New Item" flag show for 30 days. After looking and LOOKING, no luck. I finally found my answer a few hours ago! Here's how you do it.

This works in both SharePoint 2010 and 2007.

Open up command line and make sure STSADM is in your path.

Now, type the following

stsadm -o setproperty -propertyname days-to-show-new-icon -propertyvalue 30 -url http://mysite/

You can make the amount as much as you like, so don't think you have to choose 30 days as your value too.
