Windows Vista 32bit or 64bit?

Which is better for my new mac book pro, Windows Vista 32bit or 64bit Ultimate? All I care about is all of my programs and games working properly. And what does 86x mean? Will one version of the bits work faster than the other?

Hi Konnexion,
There is another more important limit with 32-bit versions of Windows, and that is the limit of 2 GBS of RAM per process. Unless some tricks and tweaks are used (which can result in reduced stability), no matter how much physical RAM is installed, a single application can't use more than 2 GBs. This is important for applications that can use large amounts of RAM like video and picture rendering apps, and even some games these days (particularly in Vista).
On the other hand, the 64-bit version of Vista has a number of additional security enhancements over the 32-bit version, such as address-space layout randomization, mandatory driver signing. If you have the RAM (at least 4GBs) and games are not a priority, I would actually recommend using the 64-bit version. Of course, why would you be using Boot Camp, if it weren't for games LOL?

Windows Vista Update posts 64bit driver for Qosmio F30 32bit Vista

Hello
Today I've noticed that Windows Vista update is posting the wrong update for one of Qosmio F30 drivers.
I have Windows Vista 32Bit but Windows Update post a 64bit version of the driver.
see the screenshot [Here|http://imagefilehost.googlepages.com/f30Wrongupdate.jpg]
Any idea?

hmm... this is strange ?:|
The Toshiba x64 ACPI compliant driver means definitely a 64bit version!!!
I dont know why the Vista driver update notification reports an 64bit driver for a 32bit OS but usually the 64bit driver shouldn't be compatible with the 32bit OS.
However, the case seems to be clear dont install it if the driver is not designed for your OS.

Treo 750 syncing w/ Windows Vista 32bit

I have a Treo 750 that I had synced with windows xp. Ever since I "upgraded" to windows vista I have not been able to sync. The computer won't even recognize the phone as connected. Here is what I have and what I have tried already. I have, as mentioned, the Treo 750 running windows mobile 5.0/ the laptop was running xp which I had no problems setting up and syncing. I now have window vista 32bit I guess since when I tried downloading WMDC 64bit it wouldn't support the download, so I have WMDC 32bit. When I downloaded WMDC the treo was connected through a usb cable. I have uninstalled and re-installed WMDC several times. Sometimes the device manager will not recognize the usb cable and sometimes it does. When it does recognize the cable it shows a bluetooth symbol and says everything is working properly but when I open up WMDC I am not connected, if I push the sync button nothing happens, if I unplug the usb cable and replug the device manager then will no longer recognize the usb cable. I have also tried everything on the support boards, help forums, you name it I have tried it except a hard reset which I don't want to do until I sync all my info first. Oh yeah the whole reason I am so desperate to sync my phone after such a long time is because my phone constantly freezes up as if I have to much going on which I don't. I have cleaned out every program not necessary so I have tons of memory, so that is not slowing down or freezing my phone. I basically have to soft reset my phone after I do or run 3-4 different applications including phone calls. ANYONE PLEASE HELP EITHER OF THESE TWO PROBLEMS BEFORE MY GIRLFRIEND DUMPS ME FOR SPENDING SO MUCH TIME ON THE COMPUTER TRYING TO FIGURE THIS STUPID THING OUT. THANKS DAVE
Post relates to: Treo 750 (AT&T)

Yeah I have tried that already no luck. Here are some other things that I forgot to mention. I have another laptop that is running windows xp, this laptop has never been synced to anything. I downloaded Microsoft Activesync but it will not connect to that either. The difference with this computer is that when I plug it into the USB port it makes a sound and when I push the usb sync button it makes a beep followed by another beep. Lastly I have another Treo (my girlfriends) that when I first tried to sync to WMDC it did not connect but after running troubleshoots I got it to work on both computers. It is so frustrating.

Changing Vista 32bit to 64bit on Satellite A500-14Q

Please let me know if I could upgrade my operating system from Windows Vista Home Premium (32bit) to Windows Vista Home Premium (64bit).
I've initially configured the laptop to 32bit and as this has a RAM of 4GB, I need to know if I could upgrade it to 64bit so that I could upgrade to Windows 7.

Hi
The recovery procedure doesnt take a long time Maybe 15 to 30 minutes. I dont know it exactly. I only make few clicks to start the procedure and then I drink a coffee. ;)
The advantages of 64bit system Well mate, I think its the support of 4GB or more RAM. On 32bit system you can only use ~3.2GB. Thats all!

Qosmio G30-204 - Should I install Windows 7 32bit or 64bit?

Hi folks,
I have a Qosmio G30-204. I've upgraded the RAM to 4GB. It has Windows Vista 32bit currently installed.
I'm planning on installing windows 7.
Can I install Windows 7 64bit or would it have to be the 32bit?
What is the difference between 32bit and 64bit anyway?

Hi
If you have upgraded the notebook to 4GB RAM you should install Windows 7 64bit. On all 32bit OS you can only use ~3.2GB due the 32bit limitation.
Thats also the difference between 32bit and 64bit, the supported RAM size. ;)

Not a lot of documentation on that one, I'm afraid, but there's some general principles troubleshooting we can try with it that might get us moving forwards.
(1) Do you currently have a copy of the Microsoft Visual C++ 2005 Redistributable Package installed on that PC? If so, try downloading the following security update:
[Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package ATL Security Update|http://www.microsoft.com/downloads/details.aspx?familyid=766a6af7-ec73-4 0ff-b072-9112bab119c2&displaylang=en#filelist]
Does iTunes install for you after applying that update?
(2) If no joy there, head into your Windows Update and click on the Update History. Have a lot of Updates also been failing for you recently? If so, doubleclick on the entries for the failed updates to bring up more information on each. What error codes appear for you for the failed updates? (Precise spelling, please.)

As I cannot recover the BIOS by normal means. Thanks.

Is Firefox 4.0 now compatible with ZoneAlarm Browser 1.5.260.0 and Windows Vista Home Premium, 64Bit System, Service Pack 2? Earlier when checking for updates there were compatibility issues. Were these issues resolved to allow me secure operation with Firefox 4.0?

HP Pavilion a1210n with Windows Vista 32bit. looking for audio drivers. Can you point me to a link?

Hello,
I have an HP Pavilion a1210n running Windows Vista 32bit. I'm missing the audio drivers and can't seem to find them. Can you point me to a link for these drivers?
Thanks, It's much appricieated!

I found this link but it doesn't talk about audio drivers in the multimedia package. Am I missing something? Does Vista need to have all OS updates installed for this to work?
Thanks again!

WIndows Vista Home Premiun 64Bits + MacBook Pro 15" Mid 2007 ( 2.4 Ghz )

Hi all,
i have a MacBook pro, ( MacBookPro3,1 ) with bootrom version MBP31.0070.B07. It is the Mid 2007 model, with 4 GB Ram. I want to install Windows for gaming purposes and i was wondering, since the documentation in the Boot Camp Support seems to be mixed, Could i install Windows Vista Home Premium 64Bits OEM, or do i need to install the 32 Bit version ? the documentation seem to suggest that the boot camp 2.1 download will offer supoort for Vista 64bits. Please help me decide what best to do here.
Thanks in advance,
Luis R. Rojas

You need 64-bit if you want to use more than 2GB RAM.

Do u use vista 32bit or 64bit software with bootcamp 1.4?

I just got a mac pro and need to use older pc software and will load vista.
macpro is 64bit computer but the bootcamp 1.4 manual says for XP use 32 bit software. Is this the same for Vista, or can I use 64bit vista software?
Many thanks

Bootcamp only supports 32bit windows and while you are correct that your computer is 64bit and can run Vista 64 its generally not recommended.
First the only real advantage to running 64bit windows is you have access to more ram. The downside is that unlike 32bit windows, 64 bit will only install Microsoft Signed drivers. This can be accomplished by searching the net, but until you get them all your computer will have less functionality.
Third (I cannot confirm this since I don't run 64bit vista) is that 64bit windows reportedly has issues running games and such.
Bottom line, problems with getting the drivers, running games just for a more maximum ram means little advantage to going that route.
Just my $.02

Windows Vista 32Bit but cannot download HD films on itunes

Hello, my first post.
I have previously purchased films from iTunes including HD films (probably 720p). I've never had a problem streaming them to my iphone via home sharing and playing them on my HDTV via the digital AV adaptor.
I recently took the plunge and bought a 2TB external hard drive in order to rip all my personal DVD collection and I also purchased an Apple TV 3 on the basis that future purchases would be from itunes in HD instead of blu-ray. However I have now noticed on itunes that I cannot purchase HD films as the option is greyed out and it merely says underneath (THE HD VERSION OF THIS ITEM IS AVAILABLE ON MAC OR WINDOWS 7 COMPUTERS WITH HDCP)
Firstly how do I find out if my computer is HDCP compatible?
Second why does my PC need this as I have no intention of watching my HD movie purchases from itunes but instead intend on streaming them via home sharing over my wi-fi network (would use ethernet but a separate apple tv 3 issue) as my Apple TV 3 is capable of dealing with 1080p and I have a 1080p HDTV connected to it with an HDMI cable?
Surely if I did watch the film via my PC then it should revert to the standard definition version.
I realise my PC has windows vista not 7 but is there a way to tweak my system to allow the purchase because my computer is certainly capable of storing HD video and streaming it to my apple TV.
If I cannot tweak my system to allow the purchase is it possible to circumvent this by purchasing the same HD film direct from my Apple TV 3?
My only question then is, if I do this how does it work?
The Apple TV 3 has no hard drive does it just stream it from the internet? or does the HD version then download to my iTunes on my PC so any future views of the HD film are instead then streamed via my home sharing as opposed to streaming/downloading it from the internet each time?
Hope the above makes sense. Would like to know a definitive answer as opposed to just guessing and purchasing films to test my theory and also don't really have to want to fork out to update my operating system from Vista to Windows 7 or 8.
Thanks in advance.
For info I have the following system. Dell Inspiron 530S Windows Vista Home Premium 32bit PC with Intel core 2 Duo CPU E8200 2.66GHz with 2GB of RAM and a 250GB HDD with about 90GB unused. My graphics card is a ATI Radeon HD 2400 Pro.

Ok I downloaded a HD film to my iPhone 4 via the itunes app. Although it took a while to download. I then loaded up iTunes on my PC and looked at my purchases section. The HD film was there ready to be downloaded from the cloud onto my iTunes. I pressed the download button but I received a warning stating that you won't be able to view the film on your PC as it's not HD compatible (words to that effect).
Next I connected my iphone to my PC and selected iPhone on the iTunes source menu and set what I wanted synced from itunes to my iPhone but I also selected "back up to this computer" (hoping everything purchased on the iPhone would back up to itunes)
It went through its process and near the end stated "Transferring purchases" it did the apps then did the HD film I purchased. Once completed I went to the movies section on the source menu in iTunes and there was my newly purchased HD film.
I tried to view the film on my PC. It came up with a warning unable to view on this computer. Not a suprise but I didn't actually want to view it on my PC I want to stream it over my wi-fi to my Apple TV which is HDCP compatible.
If it works it will be great, if not, a long winded way to go about this silly issue..
However for those of you out there without an iPhone or iPad then the only way to view HD movies on Apple TV will be to upgrade your PC/Mac and Monitors and graphics card so you can purchase the HD movie from itunes OR
purchase the HD movie from your Apple TV and each time you want to view it re-download it from the internet on ATV. Not ideal if you ask me.
I'll report back on whether ATV3 can stream this newly purchased HD film from "Computers" section. fingers crossed!
