Question: What security software do you recommend for workstation with Win2008R2 ? I need to protect only this one workstation so there is no need to have tons of features that support managing other clients. Can Forefront Client Security be installed in a way it is client that protects one local machine without installing all server infrastructure? Wouldn't FCS be kind of overkill? 

Of course I can try with some other vendors solution for Win7 security product or even something like Comodo Internet Security (free version) but since I have MSDN subscription I would like to take advantage of that.

Answer: 
I have used these [instructions](http://allthingsmarked.com/2006/10/22/howto-instantly-change-your-mac-address/) in the past and they work great

I’ve written about how to use it and how to create shortcuts to change your MAC address on-the-fly. I’ll first explain how to use Macshift for any MAC change, then I’ll show you how to make Windows shortcuts using the command-line options. I’ve also made a small script to make it easier to use, but the script isn’t necessary.

Go into properties for Network Connection. Click "Configure" next to desired network adapter and on Advanced tab you should have one field for MAC address. Usually it is named "Address", "Locally Administered Address" or something similar. There you have text box in which you can type desired MAC.

Take care that you turn off original PC (or change it's MAC also).
