My PC running the 32-bit version or 64-bit Windows?

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. Also, if you decide to switch to Windows 7 64 bit in the future, there is no way to upgrade from 32-bit Windows, clean install only.

Can I run 32-bit programs on a 64-bit computer?

Most programs designed for a computer running a 32-bit version of Windows running on a computer running 64-bit Windows versions. The notable exceptions are many antivirus programs, and some hardware drivers.

Drivers designed for 32-bit versions of Windows do not work on computers running a 64-bit version of Windows. If you try to install a printer or other device that only has 32-bit drivers available, it won't work correctly on a 64-bit version of Windows. For information on updating drivers and troubleshooting issues with device drivers for 64 bit versions of Windows, contact the manufacturer of the device or program.

I would be using a 64-bit computer?

The benefits are more obvious when you have a large amount of RAM (RAM) installed on your computer, typically 4 GB of RAM or more. In this case, because a 64-bit operating system can handle large amounts of memory more efficiently as a 32-bit, 64-bit operating system can be more responsive when you run several programs at once and switching between them frequently.

If I am running a 64-bit version of Windows, I need 64-bit drivers for my devices?

Yes. All devices devices need 64-bit drivers to work on a 64-bit version of Windows. Drivers designed for 32-bit versions of Windows do not work on computers running 64-bit Windows versions.

To learn how to check for drivers, see update a hardware driver that is not working properly or go to the website of the manufacturer of the device. You can also get information about drivers by going to the Windows 7 Upgrade Advisor website.

    If my assumption is correct, you are looking for which file to download service pack update.
    Worry not choose files. Download the .iso to the update file, either burn it or mount or extract it and install. These files are called the symbol files. They differ in the language, for example. frequency refers to the French version. They are used to debug the Service Pack and are not really necessary unless you start to run into problems and try to find solutions on your own.

  • What is the difference between Windows 7 OEM and the retail version of Windows 7?

    Can someone tell me, what is the difference between windows 7 OEM and sales vs retail?

    Can someone tell me, what is the difference between windows 7 OEM and sales vs retail?

    There is no difference in the product itself.

    Although if you get a generic OEM full version, it contains the
    even software, it has the following disadvantages compared to the
    commercial version:

    1. the biggest drawback of an OEM version (at least in the USA) is
    that its license it permanently binds to the first computer, it is
    installed on. He can never legally be moved to another computer, sold,
    or given (except with the original computer). If the computer
    dies or is stolen, your license dies with him.

    2. he can't do a clean install, not an upgrade.

    3 Microsoft offers no support for OEM versions. You cannot call their
    with a problem, but rather to secure the necessary support of your
    OEM; who take in charge may go anywhere between property and non-existent. Or
    You can get support elsewhere, like in these forums.

    Regular accumulation is the regular version at retail of Windows because most of us use (SP1 or not).

    The build Debug/Check is specifically aimed at developers who developed to make it easier for the debugging flag
    drivers to be developed. This build runs much slower due to the abduction of optimizations and other functions.

    XP Home and Professional are identical except that professional
