SYMPTOMS

Consider the following scenario:
  • You have a computer that is running Windows 7 or Windows Server 2008 R2.
  • This computer is connected to a high resolution monitor.
  • On this computer, the default dots per inch (DPI) display setting is set to a value other than 96 DPI.
In this scenario, the computer has an unexpectedly slow startup time.

CAUSE

In this scenario, the computer has an unexpectedly slow startup time after a change is made to the default DPI display setting. Then, the computer has an unexpectedly slow startup time every other time that the computer is started.

RESOLUTION

To determine whether you must apply this hotfix, verify the setting of the Make text or other items larger or smaller option on your computer. To do this, follow these steps:
  1. Click Start, and then click Control Panel.
  2. Click Hardware and Sound.
  3. Click Make text or other items larger or smaller.
If the setting is set to Smaller - 100% (default), you do not have to apply this hotfix.

If the setting is set to a different value, you may have to apply this hotfix.

If this hotfix does not resolve the problem on your computer, try to optimize Windows 7 for better performance. To do this, visit the following Microsoft Web site:
