SetACL.exe -on "[folder][file]" -ot file -actn ace -ace "n:S-1-5-32-545;p:change;s:y"
SetACL.exe -on "[folder][file]" -ot file -actn clear -clr "dacl,sacl"
SetACL.exe -on "[key]" -ot reg -actn ace -ace "n:S-1-5-32-545;p:full;s:y"
SetACL.exe -on "[service]" -ot svr -actn ace -ace "n:S-1-5-32-545;p:start_stop;s:y"For a complete list of ‘Well-known security identifiers’ (SIDs) please visit Microsoft.
