CTCP (compound tcp)

[Chrysalis]

As topic says basically microsoft made a hotfix for XP 64bit to enable compound tcp feature, also the same for windows server 2003 however XP 32bit has no such luxury, hotfix here.

I am gutted as is a very nice feature, is there some technical reason why the hotfix is 64bit only?

CTCP (compound tcp), On Xp 64 but not XP 32 why?

Because Win 2003 & XP x64 both have the same kernel, which is not the same as XP x86.

I suspect the only reason its available for XP x64 is because x64 XP is 2003 x64 rebadged, no further work would've been required to make it work. It is quite possible that the 2003 (x86) hotfix could be hacked to install on XP (x86) (they are very similar OSs), although not 100% sure it would work properly.

interesting, time for MS to put the kernel on to xp 32 then although I guess not that simple.

LOL. Don't hold your breath. It's not going to happen: they're not going to sink hundreds of millions of $ on an OS they've replaced and are going to stop selling soon. You want that kernel? It's up to you to make the move to x64...

XP is around for some years yet as I understand it. Have looked into XP64 is there any downsides, compatability for example?

As in, you're still going to have patches for a few years, yes. It's also going to be available (the home version) to system builders for the next 6 months, and a little longer exclusively (again, home version only) for ultra-low-cost PCs (dirt cheap low-spec'ed portables, like the Eee PC and the OLPC)

But it's very much on its way out. As MS' own web page says:

Direct OEM and Retail License Availability (end date)

Windows XP Professional: June 30, 2008

So whatever's on the shelves now is all that's left pretty much.

sorry I misunderstood yes it wont be sold for much longer, but will of course be supported long enough in that people can go from XP to Windows 7 bypassing vista.
