Why, after unlocking a laptop with connected monitors, all windows are on the laptop screen?

Question

Monitors

There is a laptop on Windows 10 1803 and 2 monitors are connected to it.
The work takes place on 3 screens, 1 laptop and 2 connected in the "Screen extension" mode.
When I lock the laptop (Win + L) and unlock it, then all windows open on 3 screens are on the laptop screen. After each unlocking of the laptop, you have to re-pull all the windows across the screens, which is very inconvenient because this happens 10 times a day. How to make windows stay on the screens when they are blocked, like on regular PCs.

Answer 1

I didn’t come across it, I use a second monitor and the windows are where I left them before the user was blocked.
Perhaps this happens after falling asleep and waking up from hibernation, when the monitors turn off?
In any case, you can use programs such as Autohotkey or AutoIt, so that when the event exits from hibernation or when a combination of buttons is pressed, the windows are placed in their places.

Answer 2

Faced similar, but for a long time. Since I tried Dual Monitor Tools - it perfectly works out regular on-off switching of 3-4 different variations of monitors
