How can I resolve the "resource in use" error to successfully delete a printer port in Windows 10?

To resolve the error and delete the port, follow these steps: 1. **Clear Print Queues**: Go to 'Devices and Printers', right-click any printer potentially using the port, select 'See what's printing', and cancel all documents. 2. **Stop Print Spooler Service**: Press Win + R, type `services.msc`, find 'Print Spooler', right-click and 'Stop'. Attempt to delete the port. If successful, restart the service. 3. **Remove Associated Printers**: Delete all printer objects from 'Devices and Printers' that were configured to use the specific port. 4. **Restart Your Computer**: A full system reboot can often release resource locks. 5. **Delete Drivers (Advanced)**: From 'Devices and Printers', click on any printer, then 'Print server properties' from the top bar. Go to the 'Drivers' tab and remove any drivers associated with the problematic port.
