The editions from 4.2.A to 6.2.0 come from the APPX documentation application as it stood on October 9, 2026, each with its own release's text and screenshots. Where a picture or a reference is missing from that source, the topic says so. The 4.2 and 4.1 editions are the manuals as they were published in 2006 and 2003.

Editions 4.2.A to 6.2.0 are also in the APPX documentation application at docs.appx.com.
