how can I get past this problem and still have all my windows up?
According to bapic:
I "have either /or
-Exhausted the complete Interactive shared section 2nd parameter i.e. 3072, and you would need to reduce some of your app/utilization
-One or more of your applications has a bug that it is holding more than what it ideally should and not a good option to troubleshoot
-If each of your app uses interacive service and running under local system account, make them run under another account and uncheck the option that says interact with desktop."
