There are no 64-bit versions of Windows XP Home, you're running a 32-bit operating system.

Only XP pro had a 64-bit optition.

And in any case, Microsoft stopped issuing security updates for XP Home four years ago. If your computer is connected to the internet it will be vulnerable to exploits, and you might want to consider moving to a newer Windows version.

Security updates for Windows Vista ceased a year ago.

Mainstream support for Windows 7 has ended, and that version is now in its extended support phase. That will end in January 2020.

Mainstream support for Windows 8 has ended, and extended support will end in 2023.

Not true.

A 'special' custom security download for XP last May 2017 was the last one.

That was a one-off special case to address the WannaCry/WannaCrypt ransomware attacks, and was issued in order to protect users of XP against this specific threat because so many of them (and users of other versions of Windows) had been infected.

Other than that isolated instance, what I said earlier applies - Microsoft stopped issuing security updates for XP Home in 2014.
