如果您失去或忘記了您的Windows Product Key,您可以用以下一個簡單的VBScript找回您的Product Key資料。我已試過用在執行中的Windows 10上,成功找到Product Key。

開啟「記事本」軟件
將以下文字複製並貼上「記事本」內文
儲存檔案,謹記檔案的檔案格式必須是「.vbs」。您可以用「”」符號將整個檔案名稱和格式括住,例如:「”BackupWindowsKey.vbs”」

Option Explicit
Dim objshell,path,DigitalID, Result
Set objshell = CreateObject(“WScript.Shell”)
‘Set registry key path
Path = “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\”

‘Registry key value
DigitalID = objshell.RegRead(Path & “DigitalProductId”)
Dim ProductName,ProductID,ProductKey,ProductData

‘Get ProductName, ProductID, ProductKey
ProductName = “Product Name: ” & objshell.RegRead(Path & “ProductName”)
ProductID = “Product ID: ” & objshell.RegRead(Path & “ProductID”)
ProductKey = “Installed Key: ” & ConvertToKey(DigitalID)
ProductData = ProductName & vbNewLine & ProductID & vbNewLine & ProductKey

‘Show messbox if save to a file
If vbYes = MsgBox(ProductData & vblf & vblf & “Save to a file?”, vbYesNo + vbQuestion, “BackUp Windows Key Information”) then
Save ProductData
End If

‘Convert binary to chars
Function ConvertToKey(Key)
Const KeyOffset = 52
Dim isWin8, Maps, i, j, Current, KeyOutput, Last, keypart1, insert

‘Check if OS is Windows 8
isWin8 = (Key(66) \ 6) And 1
Key(66) = (Key(66) And &HF7) Or ((isWin8 And 2) * 4)
i = 24
Maps = “BCDFGHJKMPQRTVWXY2346789″
Do
Current= 0
j = 14
Do
Current = Current* 256
Current = Key(j + KeyOffset) + Current
Key(j + KeyOffset) = (Current \ 24)
Current=Current Mod 24
j = j -1
Loop While j >= 0
i = i -1
KeyOutput = Mid(Maps,Current+ 1, 1) & KeyOutput
Last = Current
Loop While i >= 0
keypart1 = Mid(KeyOutput, 2, Last)
insert = “N”
KeyOutput = Replace(KeyOutput, keypart1, keypart1 & insert, 2, 1, 0)
If Last = 0 Then KeyOutput = insert & KeyOutput
ConvertToKey = Mid(KeyOutput, 1, 5) & “-” & Mid(KeyOutput, 6, 5) & “-” & Mid(KeyOutput, 11, 5) & “-” & Mid(KeyOutput, 16, 5) & “-” & Mid(KeyOutput, 21, 5)
End Function

‘Save data to a file
Function Save(Data)
Dim fso, fName, txt,objshell,UserName
Set objshell = CreateObject(“wscript.shell”)

‘Get current user name
UserName = objshell.ExpandEnvironmentStrings(“%UserName%”)
‘Create a text file on desktop
fName = “C:\Users\” & UserName & “\Desktop\WindowsKeyInfo.txt”
Set fso = CreateObject(“Scripting.FileSystemObject”)
Set txt = fso.CreateTextFile(fName)
txt.Writeline Data
txt.Close
End Function
執行BackupWindowsKey.vbs檔案
這樣,您就可以見到您的Windows Product Key了!您還可以將資料儲存起來,相當方便。
