Win 7 system slow or color correction trouble

If it's Windows7 's old users, from M1 to Beta, and from RC to RTM, you'll probably find that some users ' system slows down after using Windows7 's photo viewer. Especially when you use Windows Photo Viewer to view some picture format files, the system call process is obviously somewhat "obtuse", causing the Windows 7 system to slow down because it enables "use Windows 7 Monitor calibration."

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

Using the Windows7 color correction feature produces an ICC profile within the system, and then when a user browses to a picture file, the Windows7 defaults to calling the resulting ICC profile instead of calling the component that comes with the video card.

Tip: If the user has not used the color correction feature of Windows 7, 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 uses the WINDOWS7 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 into the Windows7 Control Panel, find and open "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.

The system will then pop up a dialog box "color Management-system defaults" again. In this dialog box, also switch to the advanced option, and then cancel the system by default check "Use Windows Monitor calibration", after the modification, save the settings exit
