Fix a regression that Office 2016/365 has a 640x480 main window.
Office 2016/365 hooks NtOpenKeyEx() and prevents access to SetupAPI device properties. After querying monitor information from SetupAPI failed, EnumDisplayMonitors() reports a fallback monitor of size 640x480.
IIRC when this was last brought up, the proposed solution was to do it remotely, via RPC to plugplay.exe. Arguably that's more work, but it strikes me as potentially better than getting the wineserver involved...?
As to why store the monitor information in the wineserver, it seems that EnumDisplayMonitors() reports monitors connected to current user logon session. For instance, EnumDisplayMonitors() always report one monitor when called by services.
And this could just be handled in user32, perhaps by querying the session ID or something.
Are there other reasons why it makes more sense to use the server?
