How to disable monitor calibration in Win7 system

This is another question about system speed. If you are also a loyal user of W7, from M1 to Beta, then from RC to RTM, you are constantly trying it, you may It was found that some users' system speeds slowed down after using the Windows 7 photo viewer. Especially when you use Windows Photo Viewer to view files in some image format, the system call process obviously has some “slowness”, which causes the Windows 7 system to be slowed down because it is enabled to “Use Windows 7 Display Calibration”. .





Why is it enabled to use "Windows 7 monitor calibration" will slow down the system?
Using Windows 7's own color correction function will generate an ICC profile in the system, after which, when the user browses the image file When Windows 7 defaults, instead of calling the components that come with the graphics card, it calls the generated ICC configuration file.
Small Tip: If the user has not used the color correction function of Windows 7, the ICC configuration file will not appear, and the above problem will not occur.
In this regard, the solution given by the forum users is to delete the "CalibratedDisplayProfile-0.icc" file under "X:WindowsSystem32spooldriverscolor". 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 on "Change system defaults" in the lower left corner.
Subsequently, the system will pop up a dialog box again "Color Management - System Defaults". In this dialog box, also switch to the "Advanced" option, and then cancel the system default checkmark "Use Windows Monitor Calibration", after the modification is completed, save the settings to exit. With a simple setup, the system is much faster. Sometimes it's just a small problem. As long as we find it and solve it, we will no longer worry about this problem. Pay more attention to us!
