WORKAROUND: Windows Resolution Problem on Retina screen

My Windows 7 installation on rMBP was too small to read. Setting font size bigger to default only to revert back to tiny fonts after logging in and out; in other words the settings didn't stick.

This is how I got it to work.

1. In Windows, change the screen resolution first, say to 1440 x 900.
2. Log out then Log in of Windows
3. IMPORTANT: don't drag the VM window to make it larger.
4. Uncheck "Enable Full Resolution" in VM settings.
5. Now the screen size sticks and you can drag the window size around.

6. While VM is running, check "Enable Full Resolution" on and off to see the effect.
