hi there everyone!

all other keyboard shortcuts are working, like win+e, win+r, win+x, etc.

I work with extended displays, and for the past 2 weeks when I get to the office and plug in the hdmi cable (actually a dell vga adaptor), system doesn't automatically extend displays, and when I press win+p nothing happens, so I have to right-click on the desktop and select intel> graphics options>output>extended (my windows is in portuguese, so sorry if that's not the right translation to the path).

I also have two cards in the machine, the integrated intel and an nvidia gt-740m. the system is a vostro 5470 and drivers are updated.

any ideas besides a bizarre malware that is only affecting this specific shortcut?

thanks in advance for any help.
