Default Windows 8: How Many Concurrent Windows/Monitors?

I just read Kieth's post under "PS Windows 8.1" and came away with the
impression that, out of the box, Windows 8 only allows two concurrent
windows to be open.

This sounds so radical that, if true, it seemed to warrant it's own
thread.

Only 2 concurrent windows?

Number of monitors?

You have to remember that video systems and the drivers have an impact.
When they are installed, Win is no longer "out of the box".

I wonder if there's a tutorial around somewhere
with this info in it ? :-)

This is a pretty lousy looking web page, because it
has too much decoration on it. I was hoping the rules
would be in Wikipedia, but they're not.

http://blog.laptopmag.com/use-split-...ode-windows-81

These are some basic rules (modified via the Windows 8.1 update).

1) 1280x1024 screen. One operating mode only.
Desktop mode shows N programs at once. Just like WinXP could.
Metro mode shows one running program. As if your desktop was a tablet.
Press Alt-F4 if you want to "fully exit" from the Metro program.
Use some swiping jazz, if you want to go elsewhere, or have multiple
Metro apps running, with just one Metro window on display.

2) 1366x768 or larger screen.
Now you can do "Snap". You may view a Metro program on the
right hand side of the screen, and the Desktop view (many windows)
on the left hand side.

3) Two monitors.
Now you can have the desktop on one monitor, Start/Metro on
the other monitor.

4) More monitors.
Well, who knows. Two Metro apps, one per screen perhaps ???
Who is rich enough for that many monitors ?

Windows 8.1 adds more options, changes the rules a tiny bit.
Not worth repeating. Just more variations of (1), (2), (3),
without anything important happening.

Windows 9 will allow a Metro program to run in a
window on the Desktop mode. The way it should
have been in the first place.

Suffice to way, if you used WinXP and were used to
opening N windows there, the new Windows 8/8.1/9 will
still allow N desktop windows to be opened in Desktop mode.
It means you will always have one mode, that looks like
your old OS, when it comes to opening of windows.

That's complete bull**** unless you use the Metro interface exclusively.
There, it allows you to have two Metro UI windows side-by-side but all of
those applications run in full-screen only so it kind of makes sense that
you can only fit two. If you use the Desktop (in other words, the
traditional Windows inteface), you can have a million of them open if you
so desire.

That's what I was hoping (and expected...) to hear.

I think the actual limit is 291,732 windows open. You are definitely
exaggerating.

I agree. I've had no trouble opening any number of windows in the
Desktop that I've wanted to (and of course, I pay close attention to
that 291,732-window limit).

Is there an actual limit? I'm curious now.

"That is incorrect. GNU/Linux is worse then communism because at least in

Of course, Linus is a big winner since he earns millions of dollars on the

My guess would be no. Just keep opening windows until your computer
starts to vaporize.

More seriously: Somewhere along the line there will be no memory left
to allocate or performance will begin to suffer - or both.

As for a fixed limit: my guess above could easily be wrong. (You knew
that!)

I did, but it got me wondering. It actually brought back memories of
the old goatse.cx website which would open up a crapload of windows on
your computer on top of taking it over.

Ouch! Lucky for me I missed that (or else I repressed the memory).

I could find several threads on the topic, but one answer here covers
a few possible limitations. Apparently, it's a desktop heap setting
that has the most effect. And there is a registry key where on older
OSes, you could adjust the allocation slightly. Still, in all the
threads where I've seen limits suggested, they suggested a rather
small number of windows. If would really depend, on whether modern OSes
removed the desktop heap design, as to whether that had changed or not.

http://www.vistax64.com/vista-genera...n-windows.html

For you programmer types, all it would take is a certain
one-line script, recursive, to test this :-) I'll wait
for the howls of the first victim.

When someone did that to a Unix machine at work (by accident,
they tell me), the machine became inaccessible and had to be
power cycled. We couldn't wait long enough to see if it
would be possible to stop it somehow - the admin was there
as well, invited for a good chuckle at the victims expense.
Couldn't telnet in, couldn't enter commands, etc. It's
known as a "fork bomb".

http://en.wikipedia.org/wiki/Fork_bomb

Windows won't go that way, because it'll run out of
windows first :-) Before it runs out of PIDs. It's
probably got enough file handles as well. So maybe the
reason for a low windows limit, is defensive in nature.

You pointed out something I hadn't thought of, however. The PIDs are
finite in length, so there is some kind of absolute limit on the number
of processes that can run.

Of course, not every process has a window open on the desktop. And of
course, the number of PIDs is probably unrealistically large.

In this discussion, I have the advantage of being unencumbered by the
thought process [(C) Click & Clack], so I can speculate anything.

Modern browsers usually limit the number of windows that a script can
open to avoid just this type of annoyance.
