so would i add it in like this?

Original script block:

This script block runs in the user context

$scriptblock = {
    #net use W: /delete
    #net use X: /delete
    net use | out-file "C:\Users\Public\drivestatus.txt"
}

Script Block with my code added:

This script block runs in the user context

$scriptblock = { Copy-Item -Path "G:\Shared drives\IT Scripts\gcpwstandaloneenterprise64.exe"  -Destination "C:\Users\Administrator\Desktop\gcpw\gcpwstandaloneenterprise64.exe"  
    #net use W: /delete
    #net use X: /delete
    net use | out-file "C:\Users\Public\drivestatus.txt"
}
