you can not even properly grab the edge of the window with a mouse to resize it.
Dragging a window from one screen to the other or releasing it to close to the edge ...
Yes you can.
then it will go full screen automatically ...
Windows 10 has different zones you can drag windows to in order to "snap" them into full screens, halves of a screen, or quarters of a screen. You can see an outline of where your window will land when you drag the menu bar around. If you don't want to snap it when you resize, just resize from the bottom or size it then move it in. Or, disable windows snapping. This is you not knowing how to use your tools.
the search function in the explorer is not working properly ... since windows 7 I think.
Searching in Explorer works, if you let it index your machine. I agree that it could use better search tools and sorting, however. The UI is clunky, but it works.
I close my Dell Laptop, unplug it from the docking station.
Next morning I plug it in again.
All windows are now on the screen of the laptop and not where they have been before: a nice set of chat and mail tools on the laptop screen and all the programming tools on the "external/main" screen.
That's on you, because as soon as you unplugged the laptop from the docking station you told Windows "Hey, I don't have a second monitor anymore." and it shuffled everything to the laptop's display so you can use them as soon as you open the machine.
Helllllllllo? That worked 1987 on a Mac just fine!!
And it is impossible to have a window overlap screens, the sizes get distorted ... and trust me, the resolution of the laptop is just fine, bullshit like this never happened on a Mac.
So the 10M people have no clue how a computer should work but are masochist enough to beta test ...
A Mac in 1987 wasn't a laptop with multiple displays, and you can overlap screens just fine if your screens are the same size, aligned to the proper positions, and have the same DPI. I use a triple-head display and it works just fine, though I hate overlapping windows across displays because what kind of monster would do that?
