Consider the following scenario. If the desktop heap cannot be allocated, new System log reports about the current exhaustion of the desktop heap in Microsoft Windows 2000 are not created. Therefore, you cannot detect the shortage of the desktop heap on a Windows 2000-based computer.
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.
