recoverkey_ps1

  • deschideti Windows PowerShell cu privilegii de administrator (tastatati PowerShell in Start Menu sau Start Screen, dati click-dreapta pe rezultat si selectati Run as administrator)

open-powershell

  • in fereastra deschisa tastati urmatoarea comanda

Set-ExecutionPolicy RemoteSigned

  • cand este afisata intrebarea Do You want to change the execution policy? tastati Y sau dati Enter pentru confirmare
  • apoi tastati comanda

Import-Module C:\Users\PC\Desktop\RecoverKey.ps1; Get-WindowsKey

recover-windows-product-key

In comanda de mai sus, inlocuiti C:\Users\user-name\Desktop\RecoverKey.ps1 (unde user-name este numele userului dvs) cu locatia unde ati salvat fisierul RecoverKey.ps1; de exemplu C:\Users\Stealth_2\Desktop\RecoverKey.ps1 (puteti afla foarte simplu locatia fisierului tinand apasata tasta Shift si dand click-dreapta in acelasi timp pe acesta, apoi selectand optiunea Copy as path).

Veti observa ca in Windows PowerShell vor fi afisate atat ID-ul cat si codul de licenta al sistemului dvs Windows. Succes!
