I am not able to use my Personal hotspot of my Iphone 12 pro with Windows surface pro PC.

I'm not aware of a list you can put together for the Personal Hotspot. There are no settings like that that I can find. Have you checked the network settings on the Surface. It should also have the Network troubleshooter that any Windows device has, and could possibly provide you with additional information about why it cannot connect. I do know that in the past, especially with Windows 10, if the name of the network, which is actually the name of your phone at this time, contained spaces or certain special characters, it would not connect to the network. Try temporarily changing the name of the iPhone to a single word without any spaces or special characters and test the ability to connect to the Surface.

Since you do not indicate what problems you are experiencing when you try to use the Hotspot, you can start troubleshooting here, How to set up a Personal Hotspot on your iPhone or iPad - Apple Support, then continue here, If Personal Hotspot is not working on your iPhone or iPad (Wi-Fi + Cellular) - Apple Support
