I'm using the Logitech ERGO K860 keyboard, which has the keys "opt|start" and "cmd|alt". On Windows, the "opt|start" key incorrectly became the Alt key and the "cmd|alt" key incorrectly became the Start key. I solved this issue by creating two shortcuts in Parallels Desktop preferences: (1) from Cmd to Alt, and (2) from Option to Start.
Although these shortcuts work for the most part, Alt+Tab doesn't work in Windows. It tries to switch my macOS applications, not my Windows applications. I added a new shortcut from Cmd+Tab (in macOS) to Alt+Tab (in Windows), but it still doesn't work.
