For users that are having a problem calibrating and/or reading color targets, changing the computer's performance settings could improve speed significantly.  Windows XP and Windows Vista can sometimes have memory problems especially with programs like Photoshop running in the background.  Additionally, Windows Vista can run in "Aero" mode and that can slow down the PC as well.  A typical symptom might be a ColorMunki or i1 instrument taking a very long time (minutes instead of seconds) to calibrate.  Reading the monitor profile testchart can take an extremely long time as well.  If the user is having a problem completing instrument calibration or target reading, consider the following changes to the computer's performance settings:

Windows Vista -

• Left-click Windows "Start", right-click "Computer", and left-click "Properties".
• Select the "Advanced" tab.
• Click the "Settings" button in the "Performance" section of the window.
• Select "Adjust for best performance", click "Apply", and "OK".
• Choosing "Custom" will allow the user to custom select which options to turn off or on.

Windows XP -

• Left-click Windows "Start", right-click "My Computer", and left-click "Properties".
• Select "Advanced System Settings" and navigate to the "Advanced" tab.
• Click the "Settings" button in the "Performance" section of the window.
• Select "Adjust for best performance", click "Apply", and "OK".
• Choosing "Custom" will allow the user to custom select which options to turn off or on.
