This is on Windows 8.1.1 x64 Professional.

I did a complete uninstall of DisplayFusion. Following the uninstall, I rebooted my system. The DF uninstaller does a poor job of uninstalling its folders and several registry keys. It would be great if DF did a thorough job of removing itself when directed to do so.

The following folders have to be manually removed:

C:\Users\MyAccountName\AppData\Local\DisplayFusion (16 megabytes, 5 files)
C:\ProgramData\Binary Fortress Software\DisplayFusion (Empty)
C:\Windows\System32\config\systemprofile\AppData\Roaming\DisplayFusion ( 752 kbytes, 1 file)
C:\Users\MyAccountName\Documents\DisplayFusion Backups (Empty)

The attached folder contains numerous registry keys that are left hanging in the system registry.
