Windows 7 e 8: leggere e visualizzare le chiavi di licenza

Non hai più la chiave di licenza a portata di mano, l'hai cancellata o convertita? Nessun problema! Con questo trucco puoi tirarlo fuori di nuovo. Questo trucco funziona solo con Windows 7 e 8!

Istruzioni passo passo

1. Apri PowerShell inserendo "PowerShell" nel campo di ricerca nel menu Start. Premi "Ctrl, Maiusc, Invio". Se appare una finestra di avviso, confermare con “Sì”.
2. Ciò di cui hai bisogno dopo è più libertà di comando. Immettere quindi il comando “set-executionpolicy remotesigned” e premere “Invio”. La prossima volta che ti verrà richiesto, conferma con “Sì”. In alternativa è possibile anche il comando set-executionpolicy unrestricted ".
3. Apri il Blocco note di Windows.
4. Per Windows 7, inserisci le seguenti righe nell'editor: function Get-WindowsKey { param ($targets = ".") $hklm = 2147483650 $regPath = "Software\Microsoft\Windows NT\CurrentVersion" $regValue = "DigitalProductId" Foreach ($target in $targets) { $productKey = $null $win32os = $null $wmi = [WMIClass]"\\$target\root\default:stdRegProv" $data = $wmi.GetBinaryValue($hklm,$regPath,$regValue) $binArray = ($data.uValue)[52..66] $charsArray = "B","C","D","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","6","7","8","9" For ($i = 24; $i -ge 0; $i--) { $k = 0 For ($j = 14; $j -ge 0; $j--) { $k = $k * 256 -bxor $binArray[$j] $binArray[$j] = [math]::truncate($k / 24) $k = $k % 24 } $productKey = $charsArray[$k] + $productKey If (($i % 5 -eq 0) -and ($i -ne 0)) { $productKey = "-" + $productKey } } $win32os = Get-WmiObject Win32_OperatingSystem -computer $target $obj = New-Object Object $obj | Add-Member Noteproperty Computer-Name -value $target $obj | Add-Member Noteproperty Windows-Edition -value $win32os.Caption $obj | Add-Member Noteproperty Windows-Version -value $win32os.CSDVersion $obj | Add-Member Noteproperty Bit-Version -value $win32os.OSArchitecture $obj | Add-Member Noteproperty Build-Nummer -value $win32os.BuildNumber $obj | Add-Member Noteproperty Lizenznehmer -value $win32os.RegisteredUser $obj | Add-Member Noteproperty Produkt-ID -value $win32os.SerialNumber $obj | Add-Member Noteproperty Produkt-Key -value $productkey $obj } }
5. Se utilizzi Windows 8 e 8.1, devi inserire quanto segue: Function GetWinKey { $Hklm = 2147483650 $Target = $env:COMPUTERNAME $RegPath = "Software\Microsoft\Windows NT\CurrentVersion" $DigitalID = "DigitalProductId" $Wmi = [WMIClass]"\\$Target\root\default:stdRegProv" $Object = $Wmi.GetBinaryValue($Hklm,$RegPath,$DigitalID) [Array]$DigitalIDvalue = $Object.uValue $ProductName = (Get-itemproperty -Path "HKLM:Software\Microsoft\Windows NT\CurrentVersion" -Name "ProductName").ProductName $CurrentBuild = (Get-itemproperty -Path "HKLM:Software\Microsoft\Windows NT\CurrentVersion" -Name "CurrentBuild").CurrentBuild $CurrentVersion = (Get-itemproperty -Path "HKLM:Software\Microsoft\Windows NT\CurrentVersion" -Name "CurrentVersion").CurrentVersion $PROCESSOR_ARCHITECTURE = (Get-itemproperty -Path "HKLM:SYSTEM\CurrentControlSet\Control\Session Manager\Environment" -Name "PROCESSOR_ARCHITECTURE").PROCESSOR_ARCHITECTURE $RegisteredOwner = (Get-itemproperty -Path "HKLM:Software\Microsoft\Windows NT\CurrentVersion" -Name "RegisteredOwner").RegisteredOwner $USERDOMAIN = (Get-itemproperty -Path "HKCU:Volatile Environment" -Name "USERDOMAIN").USERDOMAIN $ProductID = (Get-itemproperty -Path "HKLM:Software\Microsoft\Windows NT\CurrentVersion" -Name "ProductId").ProductId $DigiID = ConvertTokey $DigitalIDvalue $OSInfo = (Get-WmiObject "Win32_OperatingSystem" | Select Caption).Caption $CSDVersion = "" If($PROCESSOR_ARCHITECTURE -eq "x86") { $OsType = "32 Bit" } Elseif($PROCESSOR_ARCHITECTURE -eq "AMD64") { $OsType = "64 Bit" } If($CurrentVersion -eq 6.1) { $CSDVersion = (Get-itemproperty -Path "HKLM:Software\Microsoft\Windows NT\CurrentVersion" -Name "CSDVersion").CSDVersion } [string]$Value = "Infos zum Betriebssystem: `r`n" ` + "Windows-Edition : $ProductName $OsType $CSDVersion `r`n" ` + "Windows-Build-ID : $CurrentBuild `r`n" ` + "Windows-Versions-ID : $CurrentVersion `r`n" ` + "Prozessor-Architektur : $PROCESSOR_ARCHITECTURE `r`n" ` + "Produkt-ID : $ProductID `r`n" ` + "Windows-ProduktKey : $DigiID `r`n`r`n" ` + "Registrierter Benutzer: $RegisteredOwner `r`n" ` + "Computername : $USERDOMAIN `r`n" $Value $Txtpath = "." If($CurrentVersion -ge 6.2) { New-Item -Path $Txtpath -Name "Windows8_Key.txt" -Value $Value -ItemType File -Force | Out-Null } } Function ConvertToKey($Key) { $Keyoffset = 52 $IsWin8 = [int]($Key[66]/6) -band 1 $HF7 = 0xF7 $Key[66] = ($Key[66] -band $HF7) -bOr (($IsWin8 -band 2) * 4) $i = 24 [String]$Chars = "BCDFGHJKMPQRTVWXY2346789" Do { $Cur = 0 $X = 14 Do { $Cur = $Cur * 256 $Cur = $Key[$X + $Keyoffset] + $Cur $Key[$X + $Keyoffset] = [math]::Floor([double]($Cur/24)) $Cur = $Cur % 24 $X = $X
