How to Initiate the VMware Wins Disable Process?

Hello Guys!
Do you know what are the steps in the VMware Wins Disable Process wherein the windows key is disabled? I have VMware player with a windows XP installed in one of the virtual machines and I need to disable the windows key in XP. Can anyone please guide me on how to resolve this? Do I need to use a tool or utility to disable the key or I will just need to run a command? If so, then please provide me simple step by step instructions. I would really appreciate any help.
Thanks!
