Windows 10: CAN I UNINSTALL WINDOWS 10 AND INSTALL WINDOWS XP?

I HAVE A DELL OPTIPLEX 755 PC WITH WINDOWS 10 INSTALLED ON IT. THE REASON I BOUGHT THIS PC IS BECAUSE I NEEDED A PC WITH A PARALLEL PRINTER PORT FOR MY CNC MACHINE. I NEED TO INSTALL WINDOWS XP ON IT AND UNINSTALL THE WINDOWS 10 BECAUSE I NEED TO INSTALL MACH 3 CNC SOFTWARE ON IT. WINDOWS 10 DOESN'T LIKE MACH 3 AND MACH 3 DOESN'T LIKE WINDOWS 10. IT HAS SOMETHING TO DO WITH THE DRIVERS. I READ THAT WINDOWS 10 THINKS THE DRIVER FOR MACH 3 IS A VIRUS AND WILL NOT DOWNLOAD IT WHICH DEFEATS THE PURPOSE OF ME GETTING THIS OLDER PC. THE PC WILL NOT BE CONNECTED TO THE INTERNET. CAN A PERSON UNINTAL

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.
