Enabling "Use Windows 7 Monitor calibration" slows down the system

If you're an old Windows 7 user, from M1 to Beta, and from RC to RTM, you'll probably find that some users ' system slows down after using XP Photo Viewer. Especially when you use Windows Photo Viewer to view some picture format files, the system call process is obviously somewhat "slow".

The reason for this is that Windows 7 systems are slowed down because the "use Windows 7 Monitor calibration" is enabled.

Small knowledge: Why is the "use Windows 7 Monitor calibration" enabled to slow down the system?

Using the Windows 7 Ribbon Color Correction feature produces an ICC profile within the system, and then when a user browses to a picture file, Windows 7 defaults to calling the resulting ICC profile instead of calling the component that comes with the video card.

Small tip:

If the user has not used the color correction function, the ICC profile will not appear, and this problem will not occur.

For this, there are forum users to give the solution is to delete "X:windowssystem32spooldriverscolor" under the "CALIBRATEDDISPLAYPROFILE-0.ICC" file. But this method can only temporarily solve the problem, can not be solved once and for all. Because once someone is using the Windows 7 system's own color correction feature on your computer again, the file will be generated again. The author thinks, the better method should be this:

Go to the Control Panel and locate and turn on color management. In the Color Management dialog box that opens, switch to the Advanced tab, and then click Change System Defaults in the lower-left corner.

Change system defaults

Next, a dialog box, "Color Management-system defaults," will pop up again. In this dialog box, also switch to the advanced option, and then cancel the system by default check "use Monitor calibration."

Cancel the system default check "Use Windows Monitor calibration"

After the modification is complete, save the settings and exit.

Note that after the official release of Windows 7, there are currently only a few video cards that conflict with the system defaults, which means that the above methods are not applicable to every WINDOWS7 user. If you disable the color correction enabled by the system by default and find that the picture appears to be abnormal, please re-enable it and manually correct it once.
