Win 7 system is slow or color correction is troublesome

If it is an old user of Windows 7, from M1 to Beta, then from RC to RTM, you are constantly trying it out, you may find that you are using Windows 7 photo viewer After that, some users' system speed will be slower. 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”. . Tip: Why do you enable  Use Windows 7 Display Calibration" to 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, Windows 7 does not call the component that comes with the graphics card by default, but calls the generated ICC configuration file. 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:\\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 on "Change system defaults" in the lower left corner. Subsequently, the system will pop up a dialog box again & ldquo; color management - system defaults & rdquo;. 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.
