Since your iPad Pro 11" has an USB-C port, assuming your Windows PC has only USB-A ports, you need this adapter:--> https://www.apple.com/shop/product/MJ1M2AM/A/usb-c-to-usb-adapter?fnode=98679cba51df5f4038ac4c489defd71ad644c3fe263e394548c8874150062ff1af105eb142938b57e57f4880ab02c6eb4c279a3262465dfbe8bbccafc2a24d9a72ab449daf04c066f4bf120e4a355a0bb0ac0c7494759e7a025c336e819633754078a8c8ce811ffa75d28ade4f3dca48

and an USB-A to USB-A cable (male-male).

On the contrary , if your PC has USB-C ports, you don't need anything.
