Running XP on a 64bit processor computer
I have a computer which originally came witt Vista. It's a 64bit
machine. I got it with XP Pro SP3 installed. I know that XP is 32bit. I'm a little puzzled about this. Can XP (or any 32bit OS) run on a computer that has a 64bit processor? (I know you cant do it the other way. You cant run a 64 bit OS on a 32 bit machine). Does running a 32 bit OS on a 64bit machine work any better or worse than it does using an actual 32 bit computer? |

Does running a 32 bit OS on a 64bit machine work any better or worse than it does using an actual 32 bit computer? Yes provided you mean an x64 bit processor which is an extension of the 32 bit architecture. The advantage of using a 64 bit OS version (such as the final version of Win XP - Pro 64 bit) was mainly a larger address space allowing 4 GB RAM. You didn't answer the last part of James's question - "Does running a 32 bit OS on a 64bit machine work any better or worse than it does using an actual 32 bit computer?" (FWIW, I suspect it'll run about the same, other than that the 64bit machine is probably faster and may have more cores - but those are not specific to it's 64bitness. There _may_ be a few cases where the firmware in the processor makes a few operations work better, but if any, I suspect this is an insignificant proportion of the time.) -- J. P. Gilliver.

I'm a little puzzled about this. Can XP (or any 32bit OS) run on a computer that has a 64bit processor? XP comes in 32 and 64-bit versions. Yes, but the 64-bit XP version isn't all that good. Back in the era, it lacked drivers. https://en.wikipedia.org/wiki/Windows_xp "Service Pack 3 is not available for the 64 bit version of Windows XP, which is based on the Windows Server 2003 kernel." That OS has slightly different roots, than the 32-bit version. And support for environments like that, depends on the number of people adopting the product. If there aren't many users for an OS variant, you can have problems getting programs to support installation on it, and so on. I think the same was true for Windows Server 2003 users. Hardware back in that time, might lack an entry in the INF file, to get the driver to install. Those users end up "whining a lot" while using it :-) Paul |
