One way is command line as already mentioned in the above answer. Second way that I'm mentioning here is little bit for users who have limited or almost no technical knowledge or administrative access.
Follow these steps to change priority of network.
- Forget all the Wifi Networks - You can easily forget Wifi Network by LEFT clicking on Wifi Connection icon and selecting Network Settings. After that click on Manage Wifi Settings. Scroll to bottom and there you will find all your saved Wifi Networks. Left click on each and every Wifi Network and then further click on Forget button that pops out once you left click on any particular WiFi Network listed there.
- Note that WiFi networks are prioritized in the STACK Way i.e Last Saved Networks Always Proceeds over earlier saved network as the default behavior of Windows.
- Start connecting and saving all networks from the order that you want to connect least i.e save the lower priority network FIRST and then save your particular Wifi Network in the LAST.
After following the above steps you'll see that if all Wifi networks are switched on then your PC/Laptop connects to the Wifi Network that you configured LAST first!
