Re: Fasten in place
A window A/C unit is held in place by the window having been closed down upon it. Is that "fastened"? I don't think so. IMO, to be "fastened" requires the use of a "fastener," such as a nail, screw, or bolt.
{Edit to add: I did not take the phrase "screwed in window" literally. Did you mean that you used screws to hold the unit in place? If so, then I agree with Bryan.}
