32-bit and 64-bit Windows: Frequently asked questions

Here are answers to some common questions about the 32-bit and 64-bit versions of Windows.

Upgrading from the 32-bit version to the 64-bit version of Windows requires that you reformat your hard disk, install the 64-bit version of Windows, and then reinstall everything else that you had on your device.

Windows 10 and Windows 8.1

Select the Start button, then select Settings > System > About .
Open About settings

At the right, under Device specifications, see System type.

Windows 7

Select the Start button , right-click Computer, and then select Properties.

Under System, see the system type.

To install a 64-bit version of Windows, you need a CPU that’s capable of running a 64-bit version of Windows. The benefits of using a 64-bit operating system are most apparent when you have a large amount of random access memory (RAM) installed on your computer, typically 4 GB of RAM or more. In such cases, because a 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit operating system, a 64-bit system can be more responsive when running several programs at the same time and switching between them frequently.

To run a 64-bit version of Windows, your computer must have a 64-bit-capable processor. To find out if your processor is 64-bit-capable, do the following.

Windows 10 and Windows 8.1

Select the Start button, then select Settings > System > About .
Open About settings

At the right, under Device specifications, see System type.

Windows 7

Select the Start button , and then select Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, select Performance Information and Tools.

Select View and print detailed performance and system information.

In the System section, you can see what type of operating system you’re currently running under System type, and whether or not you can run a 64-bit version of Windows under 64-bit capable. (If your computer is already running a 64-bit version of Windows, you won’t see the 64-bit capable listing.)

How to determine if you have a 32-bit or 64-bit CPU

The steps to determine whether your computer has a 32-bit or 64-bit processor (CPU) depend on the type of operating system installed. Below are the steps to determine the processor type for Windows, Mac, and Linux.

Windows 8 and 10

To determine your CPU type in Windows 8 and Windows 10:

  • In the Windows search box, type system information and select the System Information icon.

Or, if you do not have a search box (because you have disabled it):

  1. Open a File Explorer window by pressing Windows Key + E.
  2. On the left, right-click This PC.
  3. In the context menu, select Properties. The System Properties window opens.

  1. In the System Properties window, find your System type, which lists your operating system and CPU type.

Earlier versions of Windows

If you are using an earlier version of Windows, follow these steps.

  • Open the Start menu >All Programs. Open the Accessories folder, then the System Tools folder. In the System Tools folder, select the System Information option.

On the right side of System Information, look for the System Type option under the Item column. The associated value, in the Value column, will tell you which type of CPU the computer has in it. If the System Type value includes «x86» in it, the CPU is 32-bit. If the System Type value includes «x64» in it, the CPU is 64-bit.

Determine if using 32-bit or 64-bit version of Windows

Microsoft Windows is available in 64-bit and 32-bit. 32-bit processors can only run 32-bit versions of Windows. However, 64-bit processors can run either the 64-bit or 32-bit versions.

To determine if the version of Windows on your computer is 32-bit or 64-bit, choose your version and follow the steps.

Determine if Windows Vista, 7, 8 and 10 is 32-bit or 64-bit

  1. Press and hold the Windows Key and the Pause key.
  2. In the System window, next to System type it lists 32-bit Operating System for a 32-bit version of Windows, and 64-bit Operating System if you’re running the 64-bit version. Below is a picture and an example of this window.

Determine if Windows XP is 32-bit or 64-bit

  1. Press and hold the Windows Key and the Pause key or open the System icon in the Control Panel.
  2. In the General tab of the System Properties window, if it has the text Windows XP, the computer is running the 32-bit version of Windows XP. If it has the text Windows XP Professional x64 Edition, the computer is running the 64-bit version of Windows XP.

Determine if Windows 2000 and prior is 32-bit or 64-bit

Windows operating systems, from Windows 95 to Windows 2000, are all 32-bit. There are no 64-bit versions of these operating systems.

Apple macOS

On the macOS, click the Apple icon in the menu bar. Select the About This Mac option in the Apple menu. On the About This Mac window, click the More Info option. Open the Hardware section and find the Processor Name attribute. Once listed, perform an Internet search, using that CPU’s processor name as a keyword, to determine if it’s a 32-bit or 64-bit CPU.

Processor 32-bit or 64-bit
Intel Core Duo or Solo 32-bit
Intel Core 2 Duo 64-bit
Any Intel Xeon processor 64-bit
Intel Core i3 64-bit
Intel Core i5 64-bit
Intel Core i7 64-bit

As seen in the above chart all the most recent Mac computers are 64-bit processors.

Linux

On the Linux operating system, access the command line interface and enter the following command.

Look for «lm» in the command output. If lm is found in the output, then the CPU is 64-bit. If you don’t see lm or see i386, i486, i586, or i686 in the output, then the CPU is 32-bit. Below is an example output of the above line with lm in the information.

Determine if the Linux kernel is 32-bit or 64-bit

Using the uname command, you can determine if your Linux kernel is 32-bit or 64-bit by running the command below.

This command would give you output similar to the example output below.

If you see x86_64 in the output, this indicates it is x86 and that it is 64-bit.

How to Tell If You Have Windows 64-Bit or 32-Bit

See if your Windows 10, 8, 7, Vista, or XP install is 32-bit or 64-bit

Not sure if your installed version of Windows is 32-bit or 64-bit?

If you’re running Windows XP, chances are it’s 32-bit. However, if you’re on Windows 10, Windows 8, Windows 7, or Windows Vista, the chance that you’re running a 64-bit version goes up considerably.

Of course, this isn’t something you want to take a guess at.

Knowing if your copy of Windows is 32-bit or 64-bit becomes very important when installing device drivers for your hardware and choosing between certain kinds of software.

One quick way to tell if you’re running a 32-bit or 64-bit version of Windows is by looking at information about your operating system installation in Control Panel. However, the specific steps involved depend a lot on which operating system you’re using.

See What Version of Windows Do I Have? if you’re not sure which of those several versions of Windows is installed on your computer.

Another quick and simple way to check if you’re running a 32-bit or 64-bit version of Windows is to check the «Program Files» folder. There’s more on that at the very bottom of this page.

Windows 10 & Windows 8: 64-Bit or 32-Bit?

You can check your Windows system type much faster from the Power User Menu, but it’s probably speedier that way only if you’re using a keyboard or mouse. With that menu open, select System and then skip to Step 4.

Choose System and Security within Control Panel.

You won’t see a System and Security link in Control Panel if your view is set to either Large icons or Small icons. If so, select System and then skip to Step 4.

Choose System.

This screen can also be opened by executing the control /name Microsoft.System command from Run or Command Prompt.

Find the System area, located under the large Windows logo. Within there, next to System type, it will say either 64-bit Operating System or 32-bit Operating System.

The second bit of information, either x64-based processor or x86-based processor, indicates the hardware architecture. It’s possible to install a 32-bit edition of Windows on either an x86 or x64 based system, but a 64-bit edition can only be installed on x64 hardware.

You should now know for certain whether Windows 10/8 is 32-bit or 64-bit

Windows 7: 64-Bit or 32-Bit?

Go to Start > Control Panel.

Choose System and Security.

Don’t see it? Just choose System and then proceed to Step 4.

Select System.

Locate the System area below the oversized Windows logo, and look for System type among the other statistics about your computer.

This will report either 32-bit Operating System or 64-bit Operating System.

There is no 64-bit version of Windows 7 Starter Edition.

Now you know whether you have Windows 7 64-bit or 32-bit.

Windows Vista: 64-Bit or 32-Bit?

Select Control Panel from the Start menu.

Choose System and Maintenance.

If you’re viewing the Classic View of Control Panel, you won’t see this link. Just open System instead and then proceed to Step 4.

Select System.

Locate the System area below the big Windows logo. Within that section is one called System type.

Look here to see if you have Windows Vista 32-bit or 64-bit, indicated by either 32-bit Operating System or 64-bit Operating System.

There is no 64-bit version of Windows Vista Starter Edition.

You should now know whether you have Windows Vista 64-bit or 32-bit.

Windows XP: 64-Bit or 32-Bit?

Select Start and then choose Control Panel.

Select Performance and Maintenance.

If you don’t see this link, open System and then go down to Step 4.

Choose System.

Locate the System area to the right of the Windows logo.

You should be on the General tab in System Properties.

Under System is basic information about the version of Windows XP installed on your computer:

  • Microsoft Windows XP Professional Version [year] means you’re running Windows XP 32-bit.
  • Microsoft Windows XP Professional x64 Edition Version [year] means you’re running Windows XP 64-bit.

There are no 64-bit versions of Windows XP Home or Windows XP Media Center Edition. If you have either of these editions of Windows XP, you’re running a 32-bit operating system.

Now you know if you’re running Windows XP 64-bit or 32-bit.

Check the ‘Program Files’ Folder Name

This method isn’t as easy to understand as using Control Panel but it does provide a quick way of checking on whether you’re running a 64-bit or 32-bit version of Windows, and is especially helpful if you’re looking for this information from a command line tool.

If your version of Windows is 64-bit, you’re able to install both 32-bit and 64-bit software programs, so there are two different «Program Files» folders on your computer. However, 32-bit versions of Windows have just one folder since they can only install 32-bit programs.

Here’s an easy way to comprehend this.

Two program folders exist on a 64-bit version of Windows:

32-bit versions of Windows have just one folder:

Therefore, if you find only one folder when checking this location, you’re using a 32-bit version of Windows. If there are two «Program Files» folder, you’re for sure using a 64-bit version.
