Will any 32-bit programs work under a 64-bit hardware/OS computer. I'd appreciate some views on this as I have lots of games in 32-bit but can't decide if it's worth upgrading the pc or buying a new one. Thanks all.

Are you running Windows XP? If so, Windows XP support has ended. As of April 8, 2014, support and updates for Windows XP are no longer available.

Even users like myself of 64 bit Win 7 and 8/8.1 are being asked to migrate to Win 10 now. So even if you decide to go to 64 bit, there's that question to consider as well.

There's some further info on this page that might help:

True. There is that to consider as well. Presently, I use Windows 7.

All 32bit applications will run just fine on a 64bit Windows, don't know about Mac/Linux but I would assume the same.

No extra programs required?

Yep they should work perfectly fine.

Its when you try to run 64bit on a 32bit when stuff wont work.

No. Microsoft has the architecture built into the OS itself and it is referred to WoW64 (Short for Windows x32 on Windows x64) and you can find the folder sitting in the Windows directory on a fresh install.

Technical details, Windows routes the necessary translations through these three library files.
1. Wow64.dll (the core library)
2. Wow64win.dll (the interface 32 bit programs use)
3. Wow64cpu.dll (handles the CPU modes to use)

And it's all setup up and ready to go out of the box when you install Windows x64. Users never see any difference which has lead to this information being relatively unknown despite it being documented very well by Microsoft.

You can read said documentation if you wish to dive further on the architecture (purely for information purposes only, you don't actually need to read this) : Link
