Desktop Heap Tip

Tony Schreiner's WebLog : Desktop Heap Limitations

"If you have a lot of applications open one thing you might notice is that Windows -- even XP -- will reach a point where no more windows can be opened. For me, IE hits this point after about 40-50 windows. Depending on what else you have running, you may be able to open more or less.

Usually this is not a problem, but if you find yourself running into this limit the workaround is to increase the Desktop Heap. To do this, edit the following key in the registry:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems]
Windows='%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,3072,512 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16'

and change 3072 to a larger value such as 4096. Always use caution when editing your registry; standard disclaimers apply. ..."

I've posted about desktop heap memory problems before, but I liked the above post. Short, sweat, easy to implement and to the point.

This also prompted/reminded me to make said change...
