The JPG shows the actual calculation:

Set up Monitoring Desktop Heap as Performance Alert

Find Heap Size at registion location LM\System\CurrentControlSet\Control\SessionManager\SubSystem\Windows\

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,3072,512 ....

1024k = Common Size, Do not change
3072k = Interactive Size/Desktop, Do not change
512k = Non-Intereactive Size, can change but very careful

Buffer size is 48M and everything must fit into it.

So each DeskTop Heap can support (49152-3072)/512 =(48M-3M)/512K=95 processes.

Set up Alert:
Control Panel-> Admin->Perf->Perf Log and Alert->New Alert Settings->Add Counter
->System Perf Object->Processes Counter->Add->DropDown="Alert when Value over" 95,
->Action Tab->Check "Log an entry in Event Log"->Ok, Start Alert.
