Is Win-8 "Pro" required for compatibility mode to work?

by XXPepper / May 17, 2013 11:23 PM PDT

With 7 you had to have "Pro" to get compatibility with old versions of Windows.

Is that not the case with Windows 8? Is compatibility mode available in all (non-RT) versions?

There is no XP Mode for 8.

Support at MS stores and MS support online are telling folks to use "Compatibility Mode in Windows 8". The article at this address says that and it is from May 2012.

Note that it expressly says "Windows 8" and not "Windows 8 Pro".

Very confusing. Would very much like to find definitive policy statement from MS on this.

Let's refine the types of "compatibility modes"
by wpgwpg / May 18, 2013 8:46 AM PDT

There're several types of compatibility we need to define. There's XP Mode which Bob's reply pertains to. That requires Windows 7 Pro, Enterprise, or Ultimate. It is not available with Windows 8 in any supported form. Then there are virtual modes which can run instead. MS supports Hyper-V which requires a licensed copy of XP, and a CPU feature called SLAT (Second Level Address Translation), and does not support USB. Then in virtual mode there's Oracle's Virtual Box which runs well on modern CPUs, does support USB, but also requires a licensed copy of XP. I can speak from experience that these work with XP running under them.
Finally there's what MS calls compatibility mode where you install programs to run in a mode under Windows 8 that's compatible with earlier versions of Windows. You can read a lot of details here:<div><span id="INSERTION_MARKER">
<span> From what I've read in the above link, you don't have to have Windows 8 Pro to have it, but I can't speak from experience because all I have is the Pro version.
<span> Good luck.

Windows 7 required Pro and above to
by orlbuckeye / May 19, 2013 10:50 PM PDT

run XP mode which is XP in a virtual machine. It doesn't anything to do with compatibility mode. This is used to run 16 bit applications. Some of those programs would run in 32 bit Windows 7 but not 64 bit so the VM is required to run them.

Windows 8 doesn't have XP mode. But you do have to have to have Windows 8 Pro to run Hyper-V which is a virtual machine. The difference is XP mode comes with XP for no charge and Hyper-V doesn't come with XP and to install XP you need to purcahse it separately.
