As of the end of March, 2007, 129 applications were certified or designed for Windows Vista, and 922 applications worked or were compatible with Windows Vista. Think that’s a lot? Well, it does add up to over 1,000 applications you can run on Windows Vista with few, if any, issues. But, given that there are tens of thousands of applications designed for Windows, this first thousand is just a drop in the bucket.
Many of the solutions listed here are not for those who want to take time out of their day to tinker. That’s the sad fact though. Vista is brand new, so there will certainly be some incompatibilities. At least there are some ways around it.
