Ensure 'Adjust memory quotas for a process' is set to 'Administrators, LOCAL SERVICE, NETWORK SERVICE' vulnerability for Windows 2008 R2 SQL

Question

I have a MSSQL Windows 2008 R2 server. Vulnerability for "Ensure 'Adjust memory quotas for a process' is set to 'Administrators, LOCAL SERVICE, NETWORK SERVICE'" has been found. Current settings on my server are: 'mssqlserver' 'mssqlfdlauncher' 'administrators' 'sqlserversqlagentuser$$mssqlserver' 'network service' 'local service' The CIS Microsoft Windows Server 2008 R2 Benchmark, and all other sources I have found, says remediation is to remove everything except administrators, network service, and local service. What are the possible outcomes if the other values are removed? If there are adverse side effects, how could I restore the original user/group security settings for this policy?
