I originally added this for Minecraft Education Edition to see if it would help with a sign-in issue, but it didn't seem to so I didn't create an MR for it. But this library is also used by Office and other apps. For Office, there are 2 reports[[1](https://forum.winehq.org/viewtopic.php?p=138513)][[2](https://forum.winehq.org/viewtopic.php?t=38500)] that say this is the cause of an installation crash. I can't confirm it as I don't have an Office subscription. I have some more patches for this that Minecraft Education Edition calls but I don't know if they're helpful for Office. -- v2: windows.security.authentication.onlineid: Implement IOnlineIdSystemAuthenticatorStatics::get_Default(). windows.security.authentication.onlineid: Add IOnlineIdServiceTicketRequestFactory stub interface. windows.security.authentication.onlineid: Add IOnlineIdSystemAuthenticatorStatics stub interface. windows.security.authentication.onlineid: Add stub DLL. https://gitlab.winehq.org/wine/wine/-/merge_requests/5021
