Existem algumas opções, embora eu esteja surpreso em selecionar um grupo e clicar com o botão direito do mouse não lhe dê segurança ... De qualquer forma
Confira os icacls.
icacls c:\windows\* /save AclFile /T
- Will save the ACLs for all files under c:\windows
and its subdirectories to AclFile.
icacls c:\windows\ /restore AclFile
- Will restore the Acls for every file within
AclFile that exists in c:\windows and its subdirectories.
icacls file /grant Administrator:(D,WDAC)
- Will grant the user Administrator Delete and Write DAC
permissions to file.
icacls file /grant *S-1-1-0:(D,WDAC)
- Will grant the user defined by sid S-1-1-0 Delete and
Write DAC permissions to file.
