How To Manually Reset The Preferences File Of Adobe Photoshop On Windows

If Photoshop is generating blank color channels, inverted channels and solid filled channels when running separations or other errors that can’t be explained and a restart doesn’t help, many times its the result of a damaged preferences file.

Although resetting the Preferences can be easily done by holding down Ctrl-Alt-Shift when launching Photoshop, sometimes this doesn’t work.  This video illustrates how to manually remove this file from Photoshop. When Photoshop is relaunched, it will then generate a new clean preferences file.
