Creating a virtual machine for Windows 10 using VMware Workstation Player involves several steps:

1. Download and install VMware Workstation Player: If you haven’t already installed VMware Workstation Player, you can download it from the VMware website and follow the installation instructions.
2. Launch VMware Workstation Player: Once installed, open the VMware Workstation Player application.
3. Create a new virtual machine: From the “File” menu, select “Create a New Virtual Machine”. In the New Virtual Machine Wizard, select “Custom” and then click “Next”.
4. Select “Microsoft Windows” as the operating system and “Windows 10” as the version. Click “Next”.
5. Allocate memory: Assign the amount of memory (RAM) you want to allocate to the virtual machine. It’s recommended to allocate at least 4 GB for Windows 10.
6. Create a virtual disk: Choose “Create a new virtual disk” and select the virtual disk size. You can select the default size of 60 GB, or adjust it as needed.
7. Install the operating system: Insert the Windows 10 installation media (e.g., a DVD or a bootable USB drive) into your physical computer and select the appropriate option in the wizard. Follow the on-screen instructions to install Windows 10 in the virtual machine.
8. Configure the virtual machine: After Windows 10 is installed, you can customize the virtual machine settings such as the network configuration, audio settings, and display settings.
9. Start the virtual machine: Finally, click “Play virtual machine” to start the virtual machine and use Windows 10 as if it was installed on a physical computer.

Note: These steps are for VMware Workstation Player version 15.x. The steps may be slightly different for earlier versions of the software.
