I think most will google that title before hand so my reply will try to avoid prior answers.
From what I see, Microsoft did move settings about and outright removed some settings we had before so we go get some other app to tinker or read about registry changes.
In previous versions, it simply went by changing the size of the font, and accordingly, the title bar became lower. Or was it possible to use Windows Aero Tweaker, a handy utility that could change windows edges altogether. Win10 has already lowered the window edges to a minimum, but the upper bar does not shrink. Does anyone know how to do it?
For some maybe a trifle, but the desktop space is never enough for precision work in a cad or with photos. E.g. office 2010 is a negative example of how screen design can look like (Even for some good reasons-tablets, etc.)
thanks for any advice
