svchost and windows operating system question?

I have installed CIS 3.8 today and as I went for a clean install I deleted all folders and therefore didn’t keep my CIS version 3.5 settings. Not a problem as I just went to Kyles tutorials in the guides section and reapplied them all. I also wanted to set svchost as outgoing only but when I go into Firewall>Network Security Policy I can’t find an entry for svchost in there. I then noticed that in my Firewall Event logs I have loads of blocked entries from Windows Operating System and C:\Windows\System32\svchost.exe. Does this have any bearing on why I cannot see either of the above in the Firewall NSP?. If not how do I get svchost.exe to appear in the NSP in order to apply the outgoing only rule?.
