Aren't we disabling UAC / LUAFV on a per-executable basis using manifests? At least the blog article at [1] suggests that we are in fact doing it the right way using our script to genera the manifests [2]. Oh but wait, we're not generating a manifest for git.exe itself, only for executables that contain "setup", "install", "update", "patch" etc. So maybe having a manifest for git.exe, too, would improve performance?
