After upgrading to windows 10, there is a misalignment of winmove.
For a start,
try winmove, 0,0
you would notice that the top left corner of the window is not exactly at the top left of the screen.
It is off by a few the pixels from the left.
The pixel offset is different for different applications, e.g. chrome & word 2016.
What I guess is that windows 10 is deliberately displacing windows to enable the sticky edges of windows to facilitate aero snap.
(I could be totally wrong)
I seek your help to deal with this offset.
