I just saw that there is a second package for WinSCP in the Microsoft Store.
I don't know if it's legit or scam, but it's not good to have the same product twice nonetheless.
"WinSCP - SFTP, WebDAV, SCP and FTP client for Windows" by "Watch App"
(link removed not to promote the scam)
Just wanted to report, couldn't find anything related via the search. =)
