Renaming an in-use file is not a new Windows feature.  It's certainly
been there since Windows NT and 200, and I'm pretty sure it's in 9x as
well.  I'd check if I had a 9x box handy, but instead, Reinhard, as the
one who raised the concern, maybe you can :-)

But isn't renaming a running executable only a feature of recent Windows

OSs?

I think it didn't work with Windows NT and Windows 2000.

Bye.
