Didn't help me, unfortunately.

Here's what I did:
 1. Search up XWin.exe in the tastrt menu and open the location
 2. Windows explore opened on the start menu shortcut
 3. I right-clicked the XWin.exe shortcut and selected "Open location"
 4. This opened C:\cygwin64\bin
 5. I right-clicked C:\cygwin64\bin\XWin.exe and selected Properties...
 6. In the propertiesd dialog I selected the "Compatibility" tab
 7. In the compatibility tab I selected Windows 7 compatibility as shown here:
 8. I clicked on the "OK" button
 9. I tried running XWin.exe from the cygwin bash command line, but it exited at the same place as it always have since these problems startted:
