Someone already told you to use a vm. They’re right, but if you insist on booting to actual bare metal windows instead, consider devoting a handful of gigabytes to a dual boot setup. It’s really easy to do and will be much more reliable than the way out of service windows to go.

If you have a specific piece of software you need to run I may could help you figure out the vm setup for it. Windows VMs are my solution to running cad packages.
