deleting profiles while skipping admin

Hello folks,
i have created the following script to remove profiles from PCs, however what change would i make to skip the administrator profile?

$CLIENT = Get-Content "c:\Temp\computers.txt"
 
foreach($PC in $CLIENT){
    # Testing PC connectivity
    if(Test-Connection $PC -Count 1 -Quiet){
        # Gathering users from c:\users
        foreach($PCuser in (Get-ChildItem "\\$pc\c$\users" -Directory)){
            # delete  recursively
            RD "\\$PC\c$\Users\$($pcuser.name)\Desktop\*.*"
            RD "\\$PC\c$\Users\$($pcuser.name)\Downloads\*.*"
            RD "\\$PC\c$\Users\$($pcuser.name)\Documents\*.*"
            RD "\\$PC\c$\Users\$($pcuser.name)\Music\*.*"
            RD "\\$PC\c$\Users\$($pcuser.name)\Pictures\*.*"
            RD "\\$PC\c$\Users\$($pcuser.name)\Videos\*.*"
        }
    }else{
        Write-Warning "$PC is offline"
    }
} 

Select all Open in new window
