Windows 7 64 bit comes in handy when you need to deal with at least 4 GB of RAM or more. Windows 7 32 bit can use up to 3.2 GB of RAM. Because the address space of memory is much larger for 64-bit Windows, this means that you need two times more memory than the 32-bit Windows to accomplish some of the same task, but you are able to do much more, you can have more apps open, do things like run a virus scan in the background it will affect the performance of your system. 64-bit Windows 7 is safer too, malicious code cannot easily infiltrate it, drivers are more reliable because they must be signed before it can work with 64 bit Windows 7.

Regarding compatibility, you need device drivers 64-bit hardware devices, you may have. In addition, there is no 16-bit subsystem in Windows 7 64-bit, which means, your applications must be 32-bit only, not 16-bit Installer or programs uninstaller.

The upgrade of Windows Vista

When important changes to your computer, for example an upgrade, it is always recommended that you back up your system before installing a new version of Windows. In your case, you can upgrade to Windows 7 depending on the edition and the architecture of Windows Vista, you have installed. If you are running a 32-bit version of Vista and upgrade to a 64-bit (Windows 7 edition) version, you'll have a pure make install, it is the opposite case.

If you are using Windows Vista Home Basic or Premium consumer editions, you can only upgrade to Windows 7 Home Premium or Ultimate. In addition, you can make downgrades, which means, if you are running Windows Vista Ultimate Edition now, you cannot downgrade to Windows 7 Home Premium. You perform logical upgrades:

Windows Vista Home Basic > Windows 7 Home Basic, Premium or Ultimate

Windows Vista Edition Home Premium > Windows 7 Home Premium or Ultimate

Windows Vista Business > Windows 7 Professional, enterprise or ultimate edition

Windows Vista Business > Windows 7 Enterprise

Windows Vista Ultimate > Windows 7 Ultimate.

The upgrade to Windows XP?

Please read these instructions carefully and completely before you begin installing Windows 7: there are important steps that you must follow to upgrade your PC from Windows XP to Windows 7 in order to preserve your files and settings.

Before you begin, you'll need to backup all your data to an external storage device, and you will need all the installation discs for the programs that you want to keep. Please make sure that you have an external hard drive (see details below).

More detailed instructions are available at windows.microsoft.com/upgrade-windows-xp. Here are the basic steps.

1. start Windows Upgrade Advisor (windows.microsoft.com/upgradeadvisor) to see if there are known issues that may affect the installation and the question of whether you should install the version of 32 or 64 bit Windows 7.

2 back up your files and settings on an external hard drive using Windows Easy Transfer (windows.microsoft.com/windows-easy-transfer). If you do not have an external hard drive, you will not be able to use Windows Easy Transfer. Alternatively, you can copy the files you want to keep on a USB stick, CD or DVD.

3. you will need to manually reinstall your programs, such as Microsoft Office, after I installed Windows 7. Gather the installation for your programs and all partner/license product key discs. You may be able to download programs from the Internet. For example, Windows Live Messenger can be installed from the download.live.com/messenger.

4. Insert the Windows 7 DVD in your PC. When asked "which type of installation you want. Click on "Custom (advanced)."

5. when Windows 7 is installed, use Windows Easy Transfer to restore your files and settings.

If you are not comfortable Windows 7 installation, check with a local retail or the services of the PC company store to see if they offer upgrade services.
