Windows 7 system slow or color correction

If you are an old Windows7 user, from M1 to Beta, then RC to RTM, you are constantly trying, you may find that you are using Windows7 photos After the viewer, some users' system speed will be slower. Especially when you use Windows Photo Viewer to view files in some image formats, the system call process is obviously "slow", which causes the Windows 7 system to be slowed down because of the "Use Windows 7 Monitor Calibration".

Tip: Why does enabling "Use Windows 7 Display Calibration" slow down the system?

Using the color correction function that comes with Windows7 will generate an ICC configuration file in the system. After that, when the user browses the image file, the default of Windows7 is not to call the component that comes with the graphics card, but to call the generated ICC configuration file.

Tip: If the user has not used the color correction function of Windows7, the ICC configuration file will not appear, and the above problem will not occur.

For this, the solution given by the forum users is to delete the "CalibratedDisplayProfile-0.icc" file under "X:\\Windows\\System32\\spool\\drivers\\color". However, this method can only solve the problem temporarily and cannot be solved once and for all. This is because once someone has used the color correction feature that comes with the Windows 7 system on your computer again, the file will be generated again.

The author believes that a better method should be like this: Go to the Windows 7 Control Panel and find and open "Color Management". In the Color Management dialog that opens, switch to the Advanced tab and click Change System Defaults in the lower left corner.

Subsequently, the system will pop up a dialog box "Color Management - System Defaults". In this dialog box, also switch to the "Advanced" option, and then cancel the "Use Windows Monitor Calibration" check box by default. After the modification is completed, save the settings and exit.
