I am using Photoshop CS5.1 and I recently updated my Windows 10 pro 64 bit. I just wonder if it is the recent Windows 10 update a few days ago that had caused my color picker to be lost. After much attempt to relocate and resettings I only manage to get this one. So I just wonder if I should...
To confirm what @IamSam is pointing towards:
With Photoshop open, go to Edit > Preferences > General
Check to see if your Color Picker is set to Adobe - this will give your the PS color picker and not the system color picker that you're seeing
