How to determine the version of Windows - 32 or 64 bits


It’s easy to find the processor capacity in the Windows operating system: right-click on the icon My computer and select the item in the context menu Properties. The method works for any version of Windows (XP, 7, 8, 10). The processor of the system can be 32-bit or 64-bit. It depends on what programs, games and drivers can be installed on a particular computer.

In short, processors like x32 can only run applications designed for the appropriate bit depth. Processors such as x64 can run applications written for both 32-bit and 64-bit processors. Almost all modern games and applications are designed for 64-bit processors: this is due to the speed of data processing and the maximum possible RAM that the system can use.

The method for checking the bit capacity differs depending on the version of the system:

The easiest way to find the processor bit on a computer with Windows installed: right-click on the icon My computer on the desktop and go to Properties. The System tab will open (as in the screenshot above), where the processor capacity will be indicated.

You can open the same tab through the menu Start -> Control Panel -> Show all control panel items -> System. The processor can be single-core (x32) or dual-core (x64). The frequently encountered x86 inscription is not related to bit depth and refers to the designation of the processor architecture.

Windows XP

The morally and technically obsolete Windows XP is still actively used around the world due to the simplicity and ease of the system. Using a 32-bit (x32 or x86) version of the system limits the maximum possible amount of RAM to 4 gigabytes - this is not enough for new applications. 64-bit architecture speeds up the work and allows you to install many times more RAM (up to 32GB).

The first way to check:

  1. Open menu Startclick Run.
  2. In the window that opens, enter sysdm.cpl and press OK or Enter.
  3. Open tab General and view system information.

Two options are possible:

  • If in the OS name in the section System bit depth not specified, e.g. Windows XP Professional Version, then this is a 32-bit system. The year of manufacture does not matter.
  • Otherwise, the name of the assembly will immediately say bit depth. For example, Windows XP Professional x64 Edition. The year of manufacture of the assembly does not matter.

The second way to check:

  1. Click Start ->Run.
  2. In the window that appears, enter winmsd.execlick OK or Enter.
  3. In section System Summary find item CPU.
  4. If the processor starts with x86, means a 32-bit version of Windows XP is installed.
  5. If the value is called IA-64 or AMD64, then the processor is 64-bit.

At the moment, 64-bit versions of Windows only work with Itanium and AMD64 processors. 64-bit processors will run programs designed for the 32-bit architecture without problems, but on the contrary it will not work.

Windows 7 and Vista

In Windows 7 and Vista, as in XP, there are two standard ways to view the system capacity. The first is the “System” window in the control panel, the second is the information in the “System Information” window.

View through the Control Panel:

  1. Open Start, in the "Start Search" window, enter System.
  2. In the list that appears Programs choose System.
  3. In the window that opens, find Type of system. It will say “32-bit operating system” or “64-bit operating system”.

View through System Information:

  1. Press button Start, in the field "Start Search" enter System.
  2. In the "Programs" section, go to the section System Information.
  3. If in the section Type of system indicated x64-based PC, then the system is 64-bit.
  4. If under the heading Element indicated x86-based PC, then the system is 32-bit.

Windows 8 and 10

In the latest versions of the Windows operating system (8 and 10), the processor bit is checked using standard methods: through system information and through the Control Panel. If none of these methods help, you can always use console commands that are relevant even for Windows Server 2003.

Method 1:

  1. Press button Search. For touch devices - swipe from the right side of the screen towards the center and press Search.
  2. In the search bar enter the query system, among the options to choose Options.
  3. Click or tap an item System.
  4. Under the heading System It will be written whether 32-bit or 64-bit Windows 8/10 is installed on the device.

Method 2:

  1. Open Search, enter the query in the search bar system information.
  2. Select item Systemthen System Information ->System Summary.
  3. The "System Type" field will indicate: X64 computer or X86 computer.

The inscription “x64-based computer” means the installed 64-bit OS. The inscription “x86-based computer” means a 32-bit OS.

Windows Server 2003

Windows Server 2003 also has two standard methods for viewing the bit depth of a system (processor): in the system properties in Control panels and window view System Information.

Method 1:

  1. Click Start ->Run.
  2. Enter in the window sysdm.cplclick OK or Enter.
  3. In the window that opens, go to the tab General.
  4. If in the section System it is written Windows Server 2003 Enterprise x64 Editionthen the OS is 64 bit.
  5. If in the section System it is written Windows Server 2003 Enterprise Edition, then the system is 32-bit.

Simply put, x64 is indicated separately. If the system version is specified without bit depth, then this is a 32-bit version.

Method 2:

  1. Click Start ->Run.
  2. Enter team winmsd.exe and click OK or Enter.
  3. In the navigation area, select System Summaryfind item CPU under the heading Element.
    • If the value CPU begin with x86, then 32-bit Windows is installed on the computer.
    • If the value CPU begin with EM64T or IA-64, then the system is 64-bit.

Also, in any version of Windows, you can open Command line (Start -> Run -> cmd.exe), enter the command systeminfo and press Enter. Among other information about the system there will be a line indicating the bit depth, for example: System Type: x64-based PC.

An alternative is to run the DirectX diagnostic tool by typing dxdiag. The processor capacity will be indicated in the window System Informationin line operating system (as indicated in the screenshot).

About the change of bit depth and compatibility

To change the bit capacity, even if it is technically feasible (the processor should be able to process 64-bit addresses), it is possible only with a complete reinstallation of the operating system. All data on the computer may be lost if it is not saved to external media.

64-bit applications run faster on 64-bit processors, but on 32-bit applications they may not work at all. 32-bit applications work slower on 64-bit systems, not faster. This is due to the need to visualize the registry, but for the user the difference is completely invisible.

It should also be understood that the installer (installation files) can be designed for 32-bit systems, and the application itself - for 64-bit ones, and vice versa. Usually, when downloading installation files, it is always possible to choose not only the OS version, but also the processor capacity.

View program capacity

Everything is relatively clear with the operating system: if the 64-bit version of the OS is not installed, then the processor only supports 32-bit systems. But how do you know how a specific application was compiled if the processor capacity was not indicated in the name of the installation file?

Command line

Call the team Runholding the keys Windows + R and enter and click OK.

Look at the banner at the top of the window - it will contain information: 32-bit or 64-bit system. If this information is not available, then (in most cases) you are dealing with a 32-bit version of Windows.

Windows 10 and 8

Right-click on the Windows logo in the lower left corner of the screen and select from the menu Settings/System. In the window that opens, in the graph System Look at the information about the bit depth of the installed OS.

Keyboard shortcuts for opening this window are Windows + Pause/Break.

You can also right-click This computer > Properties.

In the window that opens, information will be mentioned: 32-bit or 64-bit system.
If there is no information, then (in most cases) this is a 32-bit version of Windows.

Press button Start > Control Panel > system and safety. In the graph System the type of system will be indicated.

How to know the bit depth of Windows Vista / 7/8/10?

All versions of Windows from Vista to 10 can find out the bitness in the system properties. Access to these properties may vary slightly between systems, but in general, just right-click on the icon to do this. My computer on the desktop and select Properties.

I will show you the example of Windows 10. There are two options to go into the system properties. The first is to right-click on the icon This computer on the desktop (if this icon is not there, then you can return it) and select Properties. The second - right-click on the button Start in the lower left corner of the screen and select System.

There is one more universal way - using the Win + Pause / Break hotkey combination. This combo immediately brings up a window with system properties in different versions of Windows. And in the section System -> Type of system You can find out the length of the Windows system.
