The usable memory may be less than the installed memory on Windows 7-based computers.



 

Computer users who want to buy Microsoft's latest operating system Windows 7 have two choices to make. First they need to decide on the edition of the operating system. At least three different editions are available for retail users, they are: Windows 7 Home Premium, Windows 7 Professional and Windows 7 Ultimate.

Windows 7 Home Premium is the cheapest of the three, Ultimate the most expensive. The more expensive editions come with additional features and it is up to the user to decide which features are needed and which are not. Most home users will be perfectly fine with Home Premium, as the Professional and Ultimate editions concentrate on offering additional features to professionals and businesses mostly.

As I have said earlier this is only one of the two decisions that users need to make. They also have to decide whether they want to install a bit or bit edition of the purchased operating system. This decision does not have to be made during the purchase as the Windows product key is valid for both bit and bit versions of the selected edition. Windows 7 bit vs bit, which should you install? If your cpu is compatible with bit editions of Windows, and you have or plan to upgrade to 4 Gigabytes of computer memory or more, then you should consider installing a bit edition of Windows 7.

Some users who need to work with bit software, very old programs or stoneage hardware may want to consider using a bit Windows 7 installation instead. Users who do not know yet may want to consider visiting or using the following resources to aid them in their decision making process:. I have installed both. And I find that I really have no problems with drivers. I have been using virtual OS for the old programs.

Otherwise, I would recommend stick with the bit. Dante, there are more reasons, for instance systems with little ram, and obviously the editions of Windows that do not ship with bit versions. But you are right, that most users should and it seems are pick the bit edition, especially if they have 4 Gigabytes of RAM or more. Another problem I noticed is that many popular programs and add-ons e. Unfortunately, almost all the new laptops come with the bit version loaded — no choice given.

It has been a big irritation for all the reasons that Martin mentions above. Windows 7 64 bit runs very slow, because it opens up most of your programs which are still 32 bit in a syswow system container or emulater in order to run the 32 bit programs. So with all that extra ram and processing power, we are running old programs inefficiently on it. I wish that I had the 32 bit version of windows 7 on my machine.

Only Microsoft has these issue, which makes the Mac look more appealing every day. All it takes to extract the desired version is a small BIT change. Further more the 64bit systems are future proofed.

The dynamic nature of computer technology and increasing need for computer resources, within the next few years 32bit will be obsolete. I enjoyed your article on 32 bit vs 64 bit, but you made no mention if someone has loaded 32 bit on his machine and runs the Win7 Ultimate, how easy or not easy is it to: a remove the 32 bit and replace with the 64 bit OR b Keep the 32 bit loaded and add or try ro the 64 bit.

Walter, think of bit and bit as different program versions that are not compatible with each other upgrade-wise. This means that you cannot upgrade from bit to bit or vice verse.

You may however be able to create a dual booting environment where you can install and load both versions. Thanks for the quick replies I got. Have I got to load the 64bit on my C drive or can I load it on an external drive? Can it be true, disk performance drops down because of 64bit addresses? I had two similar hdd hitachi and installed win7 32 on another 64bit. Somehow it seemed to me on 64bit windows loaded slightly slower.

Of course, disk test did not showed up any performance fall. I have purchased sony laptop vpceb44en. I have purchased data card of micromax MMXG but no signal. My computer is 64 bit but the data card is 32 bit so it is not supporting the laptop. Kindly advise the action for this.

Please explain why Windows 7 Ultimate x32 bit does not finish install but repeats install pattern. Save my name, email, and website in this browser for the next time I comment.
