// In several places in this file, we test the integrity level of the process
// before calling GetLongPathName. We do this because calling GetLongPathName
// when running under protected mode IE (a low integrity process) can result in
// a virtualized path being returned, which is wrong if you only plan to read.
// TODO: Waiting to hear back from IE team on whether this is the
// best approach; IEIsProtectedModeProcess is another possible solution.
