If the main reason for installing Windows 7 is to install Windows XP Mode I believe there are better alternatives available.
1. Installing Windows XP in a more advanced virtual machine such as VMware Workstation Player or Virtualbox.
2. Installing Windows XP Mode in Windows 10 Hyper-V. From a bit of research this can be accomplished if you have a Hyper-V capable CPU and Windows 10 Pro of which the latter you already have. There are then
instructions to install XP as a virtual machine, but doing this requires more steps and doesn't accomplish much more than what VMware or Virtualbox does.
