Hello there Renato,
Do you have a Samsung LCD monitor?
There is a known problem with an updated
driver that was conflicting with Windows' Color Management System.
It has to do with the color management system.
Heres how to correct it:
open control panel
type color in the search bar and click on the green color management link
in the dialog that appears tick the box under your monitor name which says "use my settings for this device"
click on the add button
There will appear a list of color profiles. You want to select sRGBIEC611966-2.1 and click ok
click on the set as default profile button and then close button
Repeat this procedure for each monitor you may have.
