Reboot - Should detect Windows machine rename as pending reboot condition

One condition that necessitates a reboot on Windows is a computer rename.

This can trivially be detected by comparing registry entries HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ActiveComputerName and HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName

The reason that this is a reboot condition is due to the Windows API call GetComputerName reading the NetBIOS name from the registry once upon boot, and that caching it for all subsequent calls. Note the documentation at https://msdn.microsoft.com/en-us/library/windows/desktop/ms724295(v=vs.85).aspx
