Hi Chris,
I’m an Independent Advisor, and I’m here to help you.
Your Surface Pro 3 does not meet the minimum system requirements for Windows 11, as Microsoft officially supports devices with at least an 8th-generation Intel processor, while the Surface Pro 3 has a 4th-generation Intel processor.
However, if you still want to install Windows 11, you can do so using some unofficial workarounds, but this is not officially supported by Microsoft and may lead to compatibility issues or lack of future updates.
Please let me know if this helps!
