Most plug-ins (flash, silverlight, java, etc) do not work in 64-bit instances of any browser (IE7, Firefox, etc). They all work fine in 32-bit instances of browsers running on a 64-bit OS.

Alrighty then!
So the trick is to install x64 Vista but run x86 apps - or run x64 apps with reduced functionality...
Are there any other surprises we should know about?
Umm...
We're talking specifically about certain plugins running in a 64-bit browser process. There are plenty of 64-bit apps that run fine, with no loss of functionality.

Big picture: was it *really* Flash, or was it some download that the site claimed was Flash? Because I've seen the bad guys (malware-writing criminals) use the ploy "oh, YOU need Flash Player, download THIS" and guess what... it's not Flash at all, it's a Trojan. If you need Flash, get it from Adobe.com.
Just checking... because as was noted, you won't launch 64-bit IE7 unless you go hunt it down in Start > Program Files > All Programs yourself.
I use 64-bit IE primarily when I'm out actively looking for malicious websites. Mandatory DEP enforcement is one reason.
Are you saying that the 32 bit IE doesn't have the same level of DEP protection as applies to the 64 bit version or all other programs in the system?
I thought DEP was basically a global setting for all programs in the OS (assuming you have it turned on with no exceptions).
If I recall correctly, though, there are some specific compile / link options that can be used to get better protection against buffer overruns and stack problems and address space randomization, though. I'll have to double check the details of those, though, again, I'd assume that any program compiled / linked with those best suggested options would perform basically comparably.... oh wait..hmm maybe the address space randomization does work better in 64 bit since it has more virtual address space to work with. I think that is a distinction IIRC.
But AFAIK it's not a DEP difference, it'd be a difference at how easy it is to exploit AFTER you've basically defeated DEP and are able to execute corrupted code/data.

On a Vista system, go to 32-bit IE7's Tools > Internet Options > Advanced menu and scroll down to here :camera:. This is 32-bit IE7's dedicated DEP control. It's not enabled by default, probably because too many browser add-ons would crash.
To enable it, right-click 32-bit IE7 and Run As Administrator, and you should be able to enable it. AFAIK, DEP is mandatorily enforced on all 64-bit apps, period, thus the use of 64-bit IE7 (in Protected Mode, of course, plus a dedicated non-Admin account and SRP) when lookin' for trouble.

To add to this...I know to some UAC is a PITA but it REALLY is a great thing. Especially when travelling to potentially unsafe places
You also need UAC to be turned on for Internet Explorer's Protected Mode to work (basically a sandbox mode).

Yep. UAC is a nice change from having to fool with RunAs in WinXP/2000, too :thumbsup: Plus it enables the file/Registry virtualization tricks to help pre-Vista software cope with the fact that apps don't get Admin rights by default anymore (which is a good thing).
As a point in case, my Mechwarrior4 games absolutely won't run from a Limited account on WinXP, but run fine from a Standard account in Vista.
why does x64 have both 32bit and 64bit versions of all its default MS apps? like theres IE 64bit and WMP 64bit as well as their 32bit counterparts.
kinda a waste of space or is there a real reason?
the only difference i see is that the 64bit versions dont run that great, like IE 64 wont load some sites

Microsoft's upgrade-path chart seems to indicate that XP Pro x64 qualifies for the upgrade to Vista, you just have to do a clean install. Any good?
I moved from 32bit Vista to 64bit in the first week of December. Been happy since. Best part is I can actually see and use all 4GB of my ram now.
Edit: btw that Flash issue is assinine. How long can it take to make a 64bit version of it?

Can a regular core duo run 64 bit stuff? core2, obviously. i'm talkin' about the generation before the 2 came to play.
A bit off topic...
How did that happen with the "accidental" release of SP1, stash...?
Not that I'm complaining, you know...
Seriously, I dont have any idea. Mistakes happen, no biggie. I'm 99% sure SP1 can't be installed without some sort of user interaction (accepting the EULA), so people were free to ignore it if they wanted to wait.
It's pretty amusing watching people work themselves into a froth trying to get it though.
Well, I have gladly accepted the "mistake".
Not that 1 month has changed anything... but who likes waiting...?
And yes, the system seems to be more responsive. :thumbsup:

It seems pointless (and stupid) to me to have an 'upgrade' path that requires a clean install tbh.
I don't want to have to go through re-installing everything over again.

I'm running XP pro at home right now. I have vista premium upgrade sitting in the box. Can I install the 64 bit version of that off the disk (or do I need to download the 64 bit version separately), and use the serial number in the box to run the 64 bit version?
ok, so a bit of research has found that yes, the code works fine on 64bit version of vista.
Now, where can i download it short of using a torrent site?
