One of many reasons that Windows users are often unwilling to move to a newer version of the operating system is application compatibility. But Microsoft's contention is this may not be as big a problem as many users fear, at least when it comes from moving from Windows 7 to Windows 10.
So far, during preview, out of 41,000 applications, customers have requested Microsoft evaluate 7,000 applications for potential compatibility concerns. Of these, 49 apps required Microsoft's assistance, officials said this week.
"Another way to look at this is that only 0.1 percent of all the apps that customers who have worked with the Desktop App Assure team to evaluate have had a compatibility issue," according to Microsoft's January 14 blog post.

FastTrack engineers won't handle the app inventory and testing to determine what does/doesn't work on Windows 10 or research which third-party ISV apps are compatible or not. They also won't provide help for app packaging-only services. (Microsoft has other tools and services, like Modern Desktop Assessment, which handles some of these tasks.
