One of the selling points of Windows 7 when it came out was the irresistible touch pack, a suite of applications designed for multi-touch, which only just came out as an optional user download. Before today, only OEMs had access to the suite, deciding whether they wanted to include the pack with their PC. There were leaks, but there no official release to the general public. You still will need a touch screen, not a mouse for the free apps to work. The pack is divided as three games and three Microsoft Surface apps, designed for Windows 7.
The download is a whopping (but understandable) 240MB, and is available at the Microsoft download site.
