Windows: There are a lot of great add-ons for Microsoft's premier productivity product, but there's no central spot to turn them on or off. TopAlt EnableDisable controls Microsoft Office add-ons with simple check-boxes.
In a way, that's all there is to it. Install the program, load it up, and you'll see all the Office programs you've installed with plug-ins active on separate tabs. My freshly-installed Office copy doesn't have a lot going on in the screenshot, but most any well-used copy will have Access, Excel, Outlook, and Word options to dig through.
EnableDisable shows you what's being loaded into your programs at startup or on-demand, and offers a description if one's embedded in the add-on. It catches both third-party plug-ins and Microsoft's own functionality extenders. The Get More Add-ins link takes you, not surprisingly, to TopAlt.com's products, but the program itself does what it promises in a seemingly safe way. TopAlt EnableDisable is a free download for Windows systems only. Topalt EnableDisable [via gHacks]
