Next generation Windows codename Longhorn will be 64bit only
They will still run 32bit stuff i hope

What about VDS on 64bit code ?

VDS is written in Delphi, and even the latest Delphi 2005 (which I have here) is still a 32-bit compiler. However, it really shouldn't make much difference to VDS since it is basically a string processing engine. VDS 6 will have the capability to handle 64-bit integer values, which would obviously be handled faster on a 64-bit processor running 64-bit code, but most of the processing time is converting numbers to and from strings. If it's speed you're after, use a language that compiles your program into binary code.

Geotrail is 100% correct. Microsoft would not shoot themselves in the foot by making people upgrade hardware to upgrade to the latest windows (although you pretty much have to anyway Wink

). They want users to be able to upgrade Windows in a simple process thus making more $ for them. Although that would help hardware makers MS would/could lose tons of sales by forcing substantial hardware upgrades.

MS is makign a 64 bit version for the desktop as well, they plan on transitioning everyone off of 32 bit to 64 bit. But 32 bit applications will be supported indefinately on the 64 bit systems.

READ Longhorn to be 64Bit only, no 32Bit

Posted by: Michiel on Nov 17, 2004 - 04:54 PM

Microsoft is currently busy working on its latest flagship operating system codename Longhorn, but for those running 32Bit hardware you may be left out when the OS is finally released.

According to sources, Microsoft Windows Longhorn will only be available for 64Bit processors and not for 32Bit. The pure reason why MS would only compile a 64Bit and not swing both ways is rather unclear at the moment. We can only speculate that since Longhorn has a few years till its official unveiling, Microsoft thinks that by that time 64Bit will be the norm and 32Bit would have fazed out.

Yes it is true you can't run the 64 bit version on a 32 bit based system such as P4 or Athlon XP. But trust me, the 32 bit version will be launched right before the 64 bit version which will be launched to their commercial customers and partners first Wink

If you don't believe me, lets make a bet. You name the $ and I'm in Wink

In the year 2006 will be dual core CPUs running 64bit with compatibility to 32bit.

So Microsoft will make an evolution step with longhorn
i dont see any point supporting pure 32bit hardware

Intel stop rising CPU clock at 3.8 GHz...

BTX design system will come...

There is no point buying a new PC at this time or the next year...if you have a GHz PC in use now...

I think the article is right. Longhorn will be 64-bit only, but it will run 32-bit apps. If you have a 32-bit processor you will have to use Windows XP. It's probably a lot more work for Microsoft to create a 32-bit version of a 64-bit OS, and it's hardly worth it if 64-bit CPUs will be obsolete by the time it comes out. Many of the 32-bit CPUs probably won't have enough power to run the new OS anyway.

jules, check out the source of the article and tell me you trust that.
Anyways, the bet is still on if anyone wants apart if it Smile

Okay whoever wants to bet $1000 that Longhorn will come in a 32bit version I'm up for that bet because IT WILL.

I don't want to claim that I have spent any amount of time researching the
new 64 bit platform because I haven't, but I felt it necessary to put forth
my two cents.

How many years has it been since the intorduction of Windows 95, about
10 years right? Prior to that all we had was a 16 bit OS. To this day I can
still write 16 bit applications that run on 32 bit machines. Why would
anyone think that just because we're moving up to a 64 bit platform that
the 32 bit apps won't work? Anyone with this notion is severly mistaken.

There will always be a reverse compatibility issue, no matter what kind of
new OSs are introduced, etc. Matter of factly, even though I run a 32 bit
machine, I'm still capable of developing 64 bit software although I can't
test the software.

My two cents...

You can also get Windows 2003 64 bit as well as 32 bit. There is a difference between 32 bit compatibility and 32 bit OS.

I've been using Longhorn with currently updated builds since early 2003. As far as I know, the 32 bit version will be the priority as the 64 bit version will be released later on after the 32 bit version has been tested in real-time enviroments. They did the same thing with the 2003 Server edition aswell.

I'm fairly certain 16 bit application compatibility has been completely removed from Longhorn, thus being able to run those apps on Longhorn is no longer possible.

Eventually MS will do the same for 32 bit apps, but it will take some time - persumably when the hardware has expanded beyong the point that current 32 bit hardware supported - (over 4 gb cpu, over 2 gb ram).

MS needed a buffer/transition between 64 bit and 32 bit OS, Longhorn will be that transition. During that time all cpu manufacturers will only be producing new 64 bit chips - thus all new pc's will be running Longhorn 64 bit.

MS probably will not develop another 32 bit OS after Longhorn, they prolly want the public to transition over to the 64 bit hardware while Longhorn will be out for a few years. I suspect 32 bit OS's will not be developed after the Longhorn OS is finished and MS will tell users who want to upgrade to the new OS that they will need new hardware as well.

By that time it will be well around 2010.

Your presumptions are pretty correct PGWARE. But, there is a way of running 16 bit apps in Longhorn. It just needs abit more fiddling as with DOS protected apps on XP. But it does work. Also, there might be an emulator out soon Wink

which will not only enable true 32 bit apps to run on the new 64 bit hardware and OS, but also 16 bit apps aswell. This is because many military branches, beleive it or not, still use those apps.

As far as I know as of now, there are not planned any SP style updates after the release of codename Longhorn, but only individual update releases. That is not definate, but what I've heard from someone not involved in the development departments.
