Using Windows 7 monitor calibration results in slow system speed

        If you are an old Windows 7 user, from M1 to Beta, then from RC to RTM, you are constantly trying it out, you may find that some users' system speed will be slow after using Windows 7 photo viewer. Especially when you use Windows Photo Viewer to view files in some image format, the system call process is obviously "slow".

above reasons that caused Windows7 system is slow, and enabled "Use Windows7 display calibration."

Tidbits: Why enable the "Use Windows7 display calibration" will slow down the system?

use Windows7 built-in color correction feature will produce a ICC profile in the system, then when users browse the image file, Windows7 default instead of calling card comes with a component, but to call generated ICC configuration file.

Tip: If you have not used the color correction function of Windows7, ICC profile does not appear, there will be no problems mentioned above.

In this regard, there is a workaround forum given by the user is deleted: "CalibratedDisplayProfile-0.icc" file in the "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.

I believe that a better approach would be this: Go to Windows7 control panel, locate and open the "Color Management" ( "Control Panel" - "Hardware and Sound" - "View devices and printers", right Click on any of the printer icons - "Printer Properties" - "Color Management" tab; an easier way is to open "Color Management" in the search bar of the "Start" menu. In the Color Management dialog that opens, switch to the Advanced tab and click Change System Defaults in the lower left corner. "- the system default color management"

Subsequently, the system will again pop up a dialog box. 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.

cancel the system default check the "Use Windows display calibration"

Please note that after Windows7 official release, currently only some graphics cards will conflict with the default settings, that is The above method is not applicable to every Windows 7 user. If you find that the picture is abnormal after disabling the color correction enabled by default in the system, please re-enable it and manually correct it once.

looks good, the operation is also simple: in Windows7 desktop, right-click "Network" (the pop-up menu) and select "Properties", the system will bring up a new dialog.

Click the bottom right of the "Wi-Fi" button, the system will pop up its "Properties" window. Click the "Wireless Properties" button in the middle section to pop up the interface. Then click the “Show Characters” item to view the corresponding wireless network password.
