Anda perlu menambahkan entri kontrol akses yang memberi Anda kontrol yang cukup, tetapi untuk melakukan itu Anda harus terlebih dahulu menjadi pemilik file. Administrator dapat menjadikan diri mereka sendiri pemilik file apa pun, tetapi proses yang melakukan penyesuaian harus memiliki SeTakeOwnershipPrivilege
hak istimewa diaktifkan. Mengaktifkan itu membutuhkan mengutak-atik kode yang tidak dikelola, yang Lee Holmes telah melakukannya untuk kita . Saya telah memformat ulang dan sedikit mengubah skripnya, yang harus Anda simpan ke file (mis. privs.ps1
):

Jika Anda belum melakukannya, Anda harus mengikuti instruksi di bagian Skrip Pengaktifan di wiki tag PowerShell . Lalu kita bisa menyatukan semuanya:
.\privs.ps1 -Privilege SeTakeOwnershipPrivilege
$acl = Get-Acl C:\Windows\HelpPane.exe
$acl.SetOwner([System.Security.Principal.NTAccount]::new('Administrators'))
$rule = [System.Security.AccessControl.FileSystemAccessRule]::new('Administrators', 'FullControl', 'None', 'None', 'Allow')
$acl.AddAccessRule($rule)
Set-Acl C:\Windows\HelpPane.exe $acl
Itu menyesuaikan ACL, memberi Anda izin untuk mengganti nama file:
Rename-Item C:\Windows\HelpPane.exe HelpPane_.exe
