How to unprotect Excel sheet without password


Unlock Excel spreadsheet with VBA code (for Excel 2010 and lower)

If you are using Excel 2010 or older version, you can unlock a password-protected sheet with the following macro.
  1. Press Alt + F11 to open the Visual Basic Editor.
  2. Right-click the workbook name on the left pane (Project-VBAProject pane) and select Insert > Module from the context menu.
  3. In the window that appears, paste in below code.

  5. Sub PasswordBreaker()
        'Breaks worksheet password protection.
     
        Dim i As Integer, j As Integer, k As Integer
        Dim l As Integer, m As Integer, n As Integer
        Dim i1 As Integer, i2 As Integer, i3 As Integer
        Dim i4 As Integer, i5 As Integer, i6 As Integer
     
        On Error Resume Next
     
        For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
        For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
        For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
        For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
     
            ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
                Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
                Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
     
            If ActiveSheet.ProtectContents = False Then
                MsgBox "One usable password is " & Chr(i) & Chr(j) & _
                    Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
                    Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
     
                Exit Sub
     
            End If
     
        Next: Next: Next: Next: Next: Next
        Next: Next: Next: Next: Next: Next
    End Sub

  1. Press F5 or click the Run button on the toolbar and wait a couple of minutes. The macro will report a cracked password, which is not the original one (always some combination of A's and B's), but nevertheless it works.

In a scenario where you have physically removed hardware from a machine you can no longer see it in device manager.  This does not mean that it is gone.  Evidence of that is, if for example you had a network card that had a Static IP address set and you remove the card and add a new one then try to set the IP address to the same as the old NIC you will get an error message. The error might look something like “The IP address 192.168.30.100 you have entered for this network adapter is already assigned to another adapter (Microsoft Virtual machine Bus Network Adapter #3) which is no longer present in the computer.  If the same address is assigned to both adapters and they both become active, only one of them will use this address.  This may result in incorrect system configuration”.  In Windows Server 2008 R2 and Windows 7 it actually gives you an opportunity to “remove the static IP configuration for the absent adapter”. If you say Yes, this will eliminate the IP conflict problem but
