如何用命令查看系统激活密钥
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。
