Well, I have a few here, let me see, :
Win7BootUpdater - Allows you to make a custom boot animation for your Windows 7, only, finding boot animations can be difficult. Deviantart can be a good site to find some. Just Google Win7BootUpdater and you'll find it.
Context Menu Editor 1.1 - this allows you to edit the right click context menu for your desktop. Me, I created links to my favorite web pages so that all I have to do is right click and connect straight there. Freeware.
Win7 Start Button Changer V 2.6 - Find and apply custom Windows 7 start orbz with ease. Another good tool to search deviantart for start orbs.
