Why do I get the message 'Initialization of USER32.dll or KERNEL32.dll' failed?

A. Every desktop object on the system has a desktop heap associatedwith it. The desktop object uses the heap to store menus, hooks, strings, andwindows.
There is soft limit on the Desktop Heap size (128KB). This can be expandedby changing a parameter in the Registry as follows:
Start the registry editor (regedt32.exe)
Move to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSessionManagerSubSystems
Double click on the Windows value
The data will be of the format:
%SystemRoot%system32csrss.exe ObjectDirectory=WindowsSharedSection=1024,3072 Windows=OnSubSystemType=Windows ServerDll=basesrv,1ServerDll=winsrv:UserServerDllInitialization,3ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=OffMaxRequestThreads=16Find the SharedSection value and add ,512 or ,1024 after the second number,for example:
%SystemRoot%system32csrss.exe ObjectDirectory=Windows SharedSection=1024,3072,1024 Windows=On SubSystemType=WindowsServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=OffMaxRequestThreads=16
Setting to ,512 will set the desktop heap to 512KB for each desktop associatedwith non- interactive window stations. 1024 would set it to 1MB.Close the registry editor
Reboot the machine
If you try and set the value to anything less than 128 then a default of 128will be used by the system, ignoring you value.
