--- Comment #3 from fiendishx@gmail.com --- To clarify I have two peculiar circumstances, the priority on which are both probably super low.
One was kind of a reverse breaking. I work on a win32 program that, for various reasons including legacy support for a system that I don't run anymore, is developed almost exclusively in Wine (wine works really well for this old 98 era MFC stuff). It never had an application manifest because it's never needed one. At least it was thought so. But because Wine reports the right version info for unmanifested applications in circumstances where Windows would not, an emergent failure on new Windows computers was masked. The solution here is obviously to just embed a manifest that turns OS support up to 11, so ultimately no real harm.
The other is, oddly enough, a demonstrator program for teaching about the value of embedding manifests in applications that someone was trying to use under similar circumstances.
