Check for reboot pending status in VB

问题

I'm currently trying to determine if a computer is in a "pending reboot" status after applying Microsoft patches in a VB program I'm writing. I have the following:

Private Sub DoesKeyExist()
    Dim regKey As Microsoft.Win32.RegistryKey
    regKey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\WindowsUpdate\\Auto Update\\RebootRequired", True)
    If regKey Is Nothing Then
        MsgBox("No reboot pending.")
    Else
        MsgBox("Reboot is pending")
    End If
End Sub

This isn't working, however, and just returns Nothing each time. Any suggestions? Thanks

By using the .LocalMachine. part you are already searching in HKEY_LOCAL_MACHINE. Try to use

regKey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\WindowsUpdate\\Auto Update\\RebootRequired", True)

instead.
