I upgraded to El Capitan, updated Parallels Desktop, and then upgraded to Windows 10. The Windows display resolution is set high, so the text in my Windows programs is so so tiny. I went into Settings in Windows 10 and changed the resolution to something lower, and the change doesn't remain after I apply it. It goes right back to 34XX by XXXX. Gotta be able to read. I have an external monitor, but even on my MacBook Pro display it's teeny tiny. Can someone help?
