How to fix wall around window

[alwaysproblems]

As we all know, happy wife happy life right?. Today she asked to to take the architrave off. I thought that plan was to buy new architrave to replace it so not too difficult.

She has now changed her mind and doesn't want architrave, she just wants a lovely plastered wall.

Given the walls are taped and filled plasterboard whats the best way to get a nice finish around the window? My initial thought was clean it all up, just slap some filler on and paint over but would love to know how to do this properly.

Thanks for any help

Thin coat stop end bead on the face and with toupret powder filler, fill and smooth over is one way
