Found Ninite while browsing a list of efficiency tools on PCWorld.com. It’s a one stop super installer, you run through the menu of available applications (subset shown below) and it builds a single MSI you can download and it is supposed to automatically disable any toolbars or similar that are ‘optional’ items during the install. I tested by selecting TeraCopy and CCcleaner, as far as I could tell it worked exactly as described.
I can see this making reinstalls a lot easier. I can also see me biasing towards tools listed here even if I’m used to using something different – maybe convenience is the trump card.
