It is possible to spoof the MAC address in Windows without going into the registry.

The network will go down during this process so it’s best to stop or wait till all downloads or any other network related activity has stopped.

Right click on Computer and select Manage.

Go to Device Manager on the left hand side list to display all the hardware usually categorised by type. Drill down into Network adapters and select the Network Interface to be changed.

Right click on the Network card and select Properties.

Go to the Advanced tab and look for Network Address in the Property: list. In some cases if this property is not listed it can be added in from the same window. Selecting the Network Address will change the right hand side to what can be changed. By default this is set to Not Present. To enter a custom MAC address select the Value radio button and enter in the MAC address with no spaces or colons in the textbox provided. OK all the windows to accept the changes. To undo this change simply change the selection of the radio buttons from Value to Not Present.

The optional steps below allows a reserved IP address to be re-assigned to the new MAC address.
Either restart of go to Start Menu > Run…. type in cmd and press enter. A DOS window should appear. type in ipconfig /release to disconnect all network adapters and ipconfig /renew to get a new IP.

There is a report generator in Microsoft Windows 7 which can help you track down what is being used in terms of power. The report tells you what is stopping the computer going into sleep mode (if sleep mode is turned on) as well as devices that do not “suspend”.

Go to the command line as an administrator. This can be achived by going to Start Menu and typing cmd in the search bar. Search for cmd.exe under Programs, hold Shift key and right click on cmd.exe. At this point you can let go of the shift key and select Run as administrator.

A dialogue box may warn you when starting the the program but OK it to start the program. Type:
powercfg -energy
and press enter to start it. The program will monitor your computer for 1 minute. In this time do what you wish.

Once it has finished it will print out the location of the report which is in a HTML (web page) format. You may need to copy to a suitable folder for your browser to open it.
