Setting programs to "outgoing only"

Can I safely set Windows-related programs like the ones below to Outgoing Only?

  • C:\WINDOWS\system32\svchost.exe
  • C:\WINDOWS\system32\lsass.exe
  • C:\WINDOWS\system32\searchprotocolhost.exe
  • System
  • C:\WINDOWS\PCHealth\HelpCtr\Binaries\HelpHost.exe
  • C:\WINDOWS\PCHealth\HelpCtr\Binaries\helpctr.exe

And how about other programs, such as games? Would that make me more secure?

Thanks
