Icons get corrupted after using Tweak UI "Rebuild Icons" function

After using the Rebuild Icons feature in Tweak UI for Windows XP, the icons may look ugly (such as the 16 color mode). This is a known issue, caused by an incorrect data assigned to Shell Icon BPP registry value. Re-setting it's to 16 resolves the problem. Use the following steps:

  • Open Registry Editor and navigate to the following key:

[HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics]

  • In the right-pane, double-click Shell Icon BPP and set it's value to 16

  • Close Registry Editor.

You will need to restart Windows for the changes to take effect. If that does not help, or to apply the change instantly, try this:
