You have 2 choices.
1. Install ESXi on the box. This will remove all other data and give you an ESXi box onto which you can install VMs that run Windows or a number of other OS. In order to use this, you will need another computer to connect to the ESXi box so you can manage it. REPEAT - THIS WILL DESTROY your current Windows box.
2. Install VMware Server on the box and then install ESXi inside that. This will allow you to look at ESXi and effectively have a virtual ESXi lab to see if it does what you want. It would be foolish to try and run anything other than evals on ESXi hosted on VMware server. REPEAT - THIS WILL BE VERY SLOW!.
