As I reported yesterday, today I'd be working on getting Hyper-V
running and install a VM WinXP. Because I'd never done that
before, I was nervous and really wasn't sure what to expect.

FWIW, I found two articles that I found very useful. They
provided step by step instructions with screenshots to highlight
the instructions.

With one or two exceptions, things went smoothly. As far as I
can tell, Hyper-V and the VM WinXP are working as expected. I
still have a long way to go, but the biggest hurdle seems to be
over.

Hyper-V requires SLAT. I could not install Hyper-V on my "pitiful"
hardware, because my processor doesn't have SLAT.

And it's handy to understand what happens when using a Hypervisor.
All OSes running on the computer are "Guest OSes". That means,
even Windows 8.1 is a Guest OS. And Windows 8.1 has the same
status as your WinXP does. The Hypervisor is the "boss", and
everything else runs underneath it.

SLAT (second level address translation) is part of enhancing
the performance of the graphics card. Since Windows 8.1 is
now a guest, it shares the video card with other OSes. It
doesn't have a privileged position, when playing a 3D game
on the computer. This could mean a reduced frame rate,
something you could have tested for, before installing
Hyper-V. (Do a before and after test, like run 3DMark
before and after, and see how much slower it is.)

So unlike other virtual machine environments, where the
"guests" go through some graphics emulation layer, the
model is a bit different when Hyper-V is involved. If
you don't notice anything, all is fine and dandy.

Note that some executables you download, they do a
check of the environment. As an example, when working
on an encrypted transport stream problem (.ts file),
I downloaded a program called TSDoctor, which has
a trial period. As is usual with programs of
unknown trust, I loaded it in a VM for testing.
It refused to run (presumably, to prevent a user like
me from using the trial period over and over again,
via throw-away VMs). If I wanted to use it, I would
be required to install it on my "main" OS.

When you load that program on your new Hyper-V setup,
it will run in no OS for trial purposes. Because the
status of all OSes, is they're all guests. You can test my
hypothesis if you want. If you purchase a license key
for the program, then you can run it where you want.
Or, so it's claimed.

So your new Hyper-V, does make a tiny difference
to programs wired up like that one. I'm sure the
author of that program, spent more lines of code
"arming and protecting it", than actually working
on transport streams.

Hi Paul,

I'm glad you saw my post my experience (all of one day so far
LOL :-) with Hyper-V. I remember you had cautioned that it might
not work.

The concept that software with trial periods might be designed to
not [snip]

If Hyper-V becomes too problematical, you might consider VirtualBox.
It is a free virtualizer, but unlike Hyper-V actually runs as an app
on the host OS, in your case W8.1, and all VMs run as Guests on the
Host.

It works very well. Easy to set up.

Way too early for me to know, especially because I'm a newbie VM
and networks. I've tried virtual box before under WinXP. So far
Hyper-V seems to work; I just don't know enough to recognize if it
works and plays "well". The articles I posted links to gave what I
thought were very clear step by step instructions to install Hyper-V
and WinXP. No significant problem, just that now I have to learn to
use it :-)
