I've looked at everything I can think of and can't find any way to change this.
It's unfortunate a simple solution is not available.
You can change the direction in Windows, see interweb for instructions, may require some regedit. Never having done it I don't know if microstation will honor it, but seems like it must.

I'm not wanting to change Windows behavior. Just MicroStation... And from what I've learned here, it's not possible.
I've had to change a few things on Windows 10 already, wish I could get rid of all references to "store" and "app".
