No problem. We ran into this issue 2 year ago when we were considering moving from XP to Vista and had 1,000 apps to test. We quickly found out that there's nothing out there that can look at every app and tell you, definitively, which apps were going to work and which were going to fail, let alone how they were going to fail. There's a few thing to look at. The first is if you're going to enable UAC and at which level. The next is how your applications are going to react in a more restricted environment and how those problems are going to be mitigated. The results of some of this testing may affect the outcome of turning on UAC! The third thing to look at is the installers for your apps. Depending on your deployment environment, your apps may not even install correctly. We found a 40-50% failure rate in our installers alone. Most of those problems were easily resolved by either retiring the app if it was no longer needed, making only simple modifications to the installers, upgrading the app to a newer version, or using App-V to run the app.
