电脑已经安装Windows10的系统，且通过不同方法，激活了系统，如何查询已激活Windows10系统的密钥呢?下面就让小编教大家如何用命令查看系统激活密钥。

用命令查看系统激活密钥的方法

制作一个【密钥查询.vbs】文件可以查询已激活系统的密钥及备份密钥。

把下面的内容复制到记事本中：

Option Explicit

Dim objshell,path,DigitalID, Result

Set objshell = CreateObject("WScript.Shell")

'Set registry key path

Path = "HKLMSOFTWAREMicrosoftWindows NTCurrentVersion"

'Registry key value

DigitalID = objshell.RegRead(Path & "DigitalProductId")

Dim ProductName,ProductID,ProductKey,ProductData

'Get ProductName, ProductID, ProductKey

ProductName = "系统名称：" & objshell.RegRead(Path & "ProductName")

ProductID = "产品ID：" & objshell.RegRead(Path & "ProductID")

ProductKey = "已安装密钥：" & ConvertToKey(DigitalID)

ProductData = ProductName & vbNewLine & ProductID & vbNewLine & ProductKey

'Show messbox if save to a file

If vbYes = MsgBox(ProductData & vblf & vblf & "要将密钥保存到文件吗?", vbYesNo + vbQuestion, "软媒魔方备份Windows密钥信息") then

Save ProductData

End If

'Convert binary to chars

Function ConvertToKey(Key)

Const KeyOffset = 52

Dim isWin10, Maps, i, j, Current, KeyOutput, Last, keypart1, insert

'Check if OS is Windows 10

isWin10 = (Key(66) 6) And 1

Key(66) = (Key(66) And &HF7) Or ((isWin10 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

If (isWin10 = 1) Then

keypart1 = Mid(KeyOutput, 2, Last)

insert = "N"

KeyOutput = Replace(KeyOutput, keypart1, keypart1 & insert, 2, 1, 0)

If Last = 0 Then KeyOutput = insert & KeyOutput

End If

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 & "DesktopWindows密钥备份.txt"

Set fso = CreateObject("Scripting.FileSystemObject")

Set txt = fso.CreateTextFile(fName)

txt.Writeline Data

txt.Close

End Function

点击记事本左下角的【文件】，在下拉菜单中点击【另存为】;

在打开的另存为窗口，点击【桌面】，在文件名(N)栏中输入：密钥查询.vbs，再点击：保存;

我们保存密钥查询.vbs文件后，在系统桌面上显示一个【密钥查询.vbs】文件图标，左键双击【密钥查询.vbs】文件图标，打开一个软媒魔方备份Windows密钥信息对话框，显示了系统名称、产品ID和已安装密钥。

如果需要保存安装密钥，点击：是(Y)，则安装密钥就会以记事本的方式保存到系统桌面上。
