in win 10, maximized window won't drag

I had the same problem too. I had turned on Snap setting: Snap Window.

This disallowed me to drag a maximized window from display 1 to display 2.

Turning off the Snap Window, I couldnt move a Maximized window.

It turns out that moving a maximized window works in Snap window mode On when you move that window to the other display fast. Moving it slow makes Windows think that you want to snap it, as if you are parking a car backwards and.. slow.

Solution to move maximized windows:

1. Keep Snap Window On
2. For Snapping a maximized window, move your mouse slow to the edge of a display
3. For moving a maximized window (to a different display), move the maximized window fast

Same...

And if I have to read one more silly reply about how people haven't been actually dragging 'Maximized' windows, I'm gonna throw up RIGHT onto my keyboard...

I maximize some windows, but did not have to click the double-box icon to reduce the size. All I had to do was drag from the title bar and the window reduced to the previous non-maximized size.

You can do that using the Snap windows feature but check out the window menu when you do that.  E.g. press Win+CursorUp ;  that snaps the window to Maximized.   Press Alt-Space to see that only the menu items I mentioned before for a maximized window are available.   When you are using the Snap windows feature with your pointer you need to drag it up first and observe the ghost maximized frame before clicking to make it snap to Maximized mode.  An analogous procedure is needed when you want to snap a window left or right.  Then I think the use of the pointer for a half screen may be clearer when snapping a window into a new mode and undoing the snap.

So, to clarify the original discussion, you weren't really dragging a maximized window you were moving your pointer in a way that looked as if you were but in fact were only doing that to change the window's mode and size.

Don't maximize it and then you can drag its edges to make it full size if you want that - and then you can move it by grabbing the title bar.

Click the little square icon to the left of the top right x on the title bar.

Lol - I have been doing the EXACT SAME THING as MeatMonger for as long as I can remember (easily the last 10 years). This is a NOTABLE change and a HUGE inconvenience. (ALL CAPS intentional, as I'm literally YELLING at my computer in exasperation)
