Thank Michael for the update.  It is handy.
When you are talking about "transparency" you mean inside Windows 10, isn't it?

I've experimented with resizing Windows 10 32bit (currently installed) using gparted and it went very well, no problems.  
I'm not sure with switching to Windows 10 64bit will help or not.
