Can i use user32.dll in Windows Service ?

Question

I need to automate mouse movement, within certain time period, for that i have wrote a Windows service with using user32.dll to automate mouse movement, it works in debug mode, but when i run it as service it doesnt seems to work. Is there any limitation for user32.dll not to work in windows service ?

Thanks in advance.

Answer 1

Typically, Windows services run in non-interactive session 0. They are isolated from the session used by a logged on interactive user and do not have direct access to the window station and desktop of that user.

However, beginning with Windows 10 you can create a Per-user service. Such a service runs in the same session as the interactive user which should provide your service with the ability to interact with the mouse.
