If you have a Windows laptop, there may be some scenarios under which you may prefer that the computer not go to sleep when you close the lid. One example could be if the laptop is connected to a dock and being used as a workstation with an external monitor. Here’s how to change that behavior:
First, what is a MAC address and why might you want to alter, clone, or spoof it? MAC stands for Media Access Control and it’s a (theoretically) unique 12 hexadecimal digit identifier for a specific piece of network hardware. An example could look like 01-23-45-67-89-AB (remember hexadecimal digits range from 0 to F).
Now why might you want to spoof, clone or alter it? Some examples may include avoiding having to register a new router’s MAC address to an internet service provider, or to obfuscate a network monitor’s ability to tie traffic to a particular piece of hardware, or to circumvent a MAC address blacklist filter preventing a device from connecting.
