Migration Assistant

How are the two devices connected? The following is from this Apple document: Move your data from a Windows PC to a Mac - Apple Support

• • Connect your Mac and PC to the same network, such as your home Wi-Fi network. Or connect an Ethernet cable between the ports on your Mac and PC to create a direct network connection. Some Mac models require an Ethernet adapter, such as the Belkin USB-C to Gigabit Ethernet Adapter or Apple Thunderbolt to Gigabit Ethernet Adapter.

You'll get a faster and more reliable transfer if you're connected via cable.

I recommend connecting the two computers using a USB cable. An Ethernet cable will also work but is slower. I recommend against using Wi-Fi or a network as they are too slow for the amount of data to be transferred and corruption of the data often occurs. As I understand it it is necessary to download a PC version of Migration Assistant which must then be installed into the PC. Have you done that?

Can you describe what you have tried?
