IRPStackSize - Windows server 2012 R2

Hi ,

we did "RAP as a Service for Failover Cluster 2012" with microsoft

one of recommended tasks is IRPStackSize  is not set to default

and as per this article  https://www.myotherpcisacloud.com/post/2012/11/11/Best-Practices-Remediation-Tips-for-Server-2012-Pt-I.aspx

"The Best Practices Analyzer says IRPStackSize   should be at 15, so I'll set it to 15. HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters\IRPStackSize. "

Now This registry is not found in Windows server 2012 R2 Cluster

So should i create it manually or its not needed ?
