(In reply to Nikolay Sivov from comment #1)
Shell_TrayWnd window is created by explorer, together with TrayNotifyWnd and ToolbarWindow32 they're supposed to form a systray windows - these last two are not created in Wine. No idea what SysPager is.
Thanks for looking into the problem.
sldProcMon.exe doesn't close immediately if SolidWorks is running. Instead it resides in tray (see attachment), so your clues about system tray are right.
sldProcMon.exe is described as "SolidWorks resource monitor" and it's purpose is to display notifications in tray if resources are low (here is example when it works https://forum.solidworks.com/message/396667).
I'm not expert but my first thoughts are that "SysPager" may be something sldProcMon.exe is checking for resource usage or foremost whether SolidWorks is running.
