How can I troubleshoot a stuck print spooler service related to printer deletion problems in Windows 10?

Go to 'Services' (search in the Start menu). Locate the 'Print Spooler' service. Stop the service. Navigate to `C:\Windows\System32\spool\PRINTERS` and delete all files and folders within that directory. Restart the Print Spooler service, and then try deleting the printer.
