Error: There are no spare stack pages. It may be necessary to increase the setting of 'MinSPs' in System.ini to prevent possible stack faults. There are currently [###] SPs allocated. 

If you receive the above message, Windows will continue to operate, however if an event causes a stack overflow, there is a large chance that Windows will crash.


Open the file SYSTEM.INI with notepad.  It is found in your Windows directory. 

Located the [386Enh] section and create a line that says "MinSPs=4 ". 

If you continue to receive the error, try increasing the number by four,  4, 8, 12, 16, 20....  until you no longer receive the error.  Please be cautious however, each spare stack requires an extra 4Kb of memory so don't set this number extremely high.
