standard account question

Hi there, we've got Windows 7 Professional and we have set up a standard account for the kids. I don't know how to limit the software they can use in their account. For example we have skype but we don't want them to have that in their account (which they do at the moment). How can we change this?

We've got Windows Live Family Safety as well for parental controls but this only affects the internet access.

Any help or pushin the right direction would be appreciated, thank you!

You might start by going to the control panel and looking at the Parental Controls. Maybe it will explain some of your options.
