Don't adjust your mind - it's reality that is malfunctioning

100% CPU-Auslastung durch den CSRSS Prozess, und Untermenüs öffnen erst nach einigen Sekunden

Affected products

  • Windows 2003
  • Tweak UI for Windows XP/2003
The CSRSS process consumes about 100% of the cpu under certain circumstances, such as opening an Outlook mail folder. Additionally, cascading menus open only with a significant delay.


One possible cause for this is the Tweak UI tool from Microsoft. This tool exposes a bug in that it sets the MenuShowDelay to zero. In fact, the lowest valid value for this setting is one. To correct this, follow these steps:
  1. Open the registry editor.
  2. Navigate to the HKEY_CURRENT_USER\Control Panel\Desktop node.
  3. Double-Click the MenuShowDelay entry.
  4. Set the value of this entry to 1.
  5. Close the registry editor.
    The changes are loaded the next time you log on to your computer.

More informations

The Tweak-UI tool from Microsoft is a tool to configure several aspects of the user interface from Windows. One of these settings is the delay for cascading menus.


The status of this problem is unknown.
