1. Advanced Uninstaller A perfect addition to any flash drive, this no-installation-required uninstaller does a fine job removing all traces of unwanted software. My favorite feature? Batch uninstall. Just tick the apps you want to ditch, and AU does the rest.
2. Dual Display Mouse Manager Dual Display Mouse Manager senses my cursor's proximity to that transition point and automatically slows it down. It's a small convenience, but an essential one for anyone rocking two (or more) monitors.
3. Dexpot No room in the budget for a second monitor? No problem: Dexpot endows your single screen with two or more virtual desktops. This popular freebie's been around for a while, but the latest version adds a killer plug-in for Windows 7 users: SevenDex, which pops up thumbnail views of your desktops when you mouse over the Dexpot taskbar icon. Sounds like a minor amenity, but trust me: it's a huge perk.
4. Universal Viewer One of those utilities that really should be built into Windows, Universal Viewer lets you view the contents of just about any file. That's great for those times when someone sends you a weirdo file attachment and you don't have the program needed to read it. And like the aforementioned Advanced Uninstaller, UV is portable (no installation required), so it runs nicely from a flash drive.
5. Wizmouse Oh, Microsoft. After all these years, Windows still isn't smart enough to detect where my cursor is pointed and make the mouse wheel work there. Instead, it works only in the window that has "focus," meaning the currently selected window. That's ludicrous! Fortunately, there's WizMouse, which activates the scroll wheel in whatever window is under your cursor, plain and simple. I started using this about a year ago; I can no longer compute without it.
