> Would you say a screen capture of Microsoft Excel is also copyright infringement?
Yeah it is. However most uses of an Excel screenshot would probably be considered fair use, and Microsoft probably doesn't care for 99% of use cases.
If you look at Wikipedia's Excel article they have more details on the legal rationale behind their use of a screenshot [1]. It looks like Microsoft allows the use of product screenshots in certain cases as well.
I also took a quick look at an Excel textbook I had on my shelf and it specifically stated in the copyright notice that they had permission from Microsoft to publish the screenshots used within.
