Registry dan permasalahannya

Anda pernah menerima pesan ini
Registry Editing Has Been Disabled By Your Administrator

Bagaimana cara mengenablenya :
Berikut cara yang paling ampuh bagi saya : pakai 2 metode ini, pertama metode 1 lihat di situs asli dan kedua yang ini :
Gunakan UnHookExec.inf dari Symantec untuk me-reset shell \ buka \ perintah kunci registri

Silahkan Copy paste kode dibawah ini pada notepad dan simpan dengan nama UnHookExec.inf pada desktop Anda. Klik kanan padanya dan pilih Install. Restart komputer Anda dan kemudian cobalah untuk membuka Registry Editor.
