RESOLUTION

 

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To resolve this behavior, use one or more of the following methods:

 

Press the F5 key to refresh the icons in the current folder.
1. Right-click the desktop and then click Properties.
2. Click the Settings tab.
3. Change the color depth from the current setting to a new setting. For example, change from Highest (32 bit) to Lowest (16 bit).
4. Click Apply, and then click Yes to accept the changes.
5. Change the color depth back to its original setting.
6. Click Apply, and then click Yes to accept the changes.

• Using Registry Editor, add the Max Cached Icons string value with a value data of 2000 to the following registry key, and then restart your computer:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion \Explorer

If the icons are still incorrect, delete the ShellIconCache file. The Max Cached Icons value data range is between 100 and 4096. The default value is 500.

The location of the ShellIconCache file is as follows for XP:

C:\Documents and Settings\Your User Name\Local Settings\
Application Data\Iconcache.db
