Sep 03, 2015 Most 32 bit apps work just fine on Windows 7 64 bit in addition to Windows 7 32 bit. Some apps that are 32 bit and utilize 16 bit installers and uninstallers will likely not work, these are apps primarily designed for older versions of Windows such as Windows 95/98.

I also use Free Macrium reflect backup and restore. It is not just matter of operating systems, it is a matter of the whole x86-64 (sometimes known as AMD64) architecture. An x86-64 cpu, which would be most 64-bit processors made today, can run in either long mode (which supports 64-bit code) or in legacy mode (which supports 32-bit and 16-bit code). Switching between modes requires a hard reset of the CPU. Windows 64-bit operating systems have built in virtualization technology which allows you to run 32-bit programs.
You can even confirm it exist for yourself. You will notice that have two Program Files folders.
One for native 64-bit programs, and another called Program Files (x86) for your 32-bit programs. If you look in the Windows folder, you will also see a SysWOW64 folder. That is where the files used for the virtualization are found.

In this case, WOW stands for Windows-On-Windows. A lot of people eventually ask 'can't windows include 16-bit virtualizaton?' They probably could, but it would mean doing a lot of work to cater to what is currently very few people. Most people who still need a 16-bit program and understand why it doesn't work natively on a 64-bit computer will also know how to install there own virtualization software, such as DOSbox or VirtualBox. With Windows 7 Pro, Ultimate, and Enterprise, Microsoft also included a free Windows XP license and access to the VirtualPC software (commonly referred to as XPmode). Now, however, they do not consider there to be enough need to continue supplying it with new OSes.

Does that mean I am not using the 64 bit even though I have a Windows 7 64 bit os installed? There are couple of other settings in the bios that are turned on.
I think one setting is called virtualization for the CPU. I have a 64 bit computer One partition is running W7 64 bit operating system Another partition is running W10 32 bit operating system with NTVDM turned on.
