The steps below this box explain how to build your own machine, which will take some time.
Mac M1, M2, or M3 Users
If you are using a Mac M1, M2, or M3 machine, you cannot use the process below because you have the newer ARM processor.Follow these instructions instead.
Here are the choices I recommend during the process:
- Step 4: Choose Professional
- Step 8: Choose UEFI
- Step 9: Choose "Auto Generate Password". Accept the default of "Remember Password and store it in Mac's Keychain".
- Step 11: Click "Customize Settings".
- After step 13, change the hard disk size to 150 GB.
- When first booting the machine, you need to click on the desktop and press Enter to boot from DVD.
- At the "Activate Windows" screen, click "I don't have a product key".
- Install "Windows 11 Pro".
- Perform a Custom installation, not an Upgrade
- At the "How would you like to set up this device?" screen, click "Set up for personal use"
If you're on MacOS, get VMware Fusion Player

Troubleshooting
In Aug, 2022 I did this process and the mouse did not work properly in the virtual machine. The solution was to remove VMware tools and install this old version instead.Download this ZIP file on your host system. Unzip it. Connect the ISO included in it to your virtual machine as a virtual CD ando install it.
