Only when you open or move files/folders from an external source in Windows, it'll give you this warning.
Actually I just discovered that isn't the case at all.
I'm having this same problem with .msc admin console files but only when run certain ways.
Ridiculous problem which I've never come across before.

P.S. System is uber clean.
No internet access while installing, and Imaging (the partitions) the entire way.
Tried numerous installs on this system and always experienced this snafu along the way somewhere.
Worse, it doesn't seem to be anything I installed, but the system itself is 'tuning' that problem in somehow.

I've been building and implementing Windoze for decades.
After NT came out I eventually noticed it seemed to 'tune itself' somehow.
For instance, certain win explorer errors that would somehow mysteriously disappear.
