Create a VM

Run VirtualBox. You will be greeted with this window:

Click "New" to create a new Virtual Machine.

Enter a name, select the ISO image we downloaded, and be sure to check "Skip unattended installation". Then, click "Next".

At least 4GB of RAM and 1 CPU is recommended, but add more if you have resources available. Then, click "Next".

At least 64GB of disk space is recommended to ensure enough space for all required development tools, including Visual Studio and the Windows Driver Kit.

Ensure the settings look correct, then select "Finish".

Start the VM by selecting "Start" with the newly created VM selected in the left-hand menu.
