Find out if a Windows program is 32-bit or 64-bit
If you have bought a computer in recent years, chance is you run a 64-bit version of Windows on it. While Microsoft is still producing 32-bit copies of Windows 10, those are sold and deployed considerably less than 64-bit copies.
Microsoft itself has not released statistics about the distribution of 32-bit and 64-bit Windows systems. If you look at Steam's Hardware Survey, as flawed as it is, you will notice that 64-bit dominates the chart.
That is somewhat to be expected considering that games benefit from a lot of memory. Still, Windows 10 64-bit dominates Steam with 48.37% currently opposed to 32-bit Windows 10 with only 1.23%. The differences are less drastically for Windows 7 (28.82% to 5.40%) and Windows 8.1 (8.59% to 1.19%).
Things are different on the software side. Plenty of high profile applications are either only available as 32-bit versions, or prioritize the 32-bit version over the 64-bit version. This has been the case for the Firefox web browser for instance. Mozilla pushed the 32-bit version of Firefox on Windows, and is just starting to change that.
Differences between 64-bit and 32-bit programs
We talked about the differences of 32-bit and 64-bit versions of Windows back when Windows 7 was released. These are still true. While there are plenty of differences, the most important ones are that 64-bit Windows and programs may use more RAM, that 64-bit Windows offers additional security benefits, and that 64-bit Windows and programs are usually larger.
Find out if a Windows program is 32-bit or 64-bit
There are several ways to determine whether a Windows process is 32-bit or 64-bit. One of the best ways is to make use of the Windows Task Manager for that.
- Use the keyboard shortcut Ctrl-Shift-Esc to open the Task Manager.
All versions of Windows highlight 32-bit processes right away in the Task Manager. Any 32-bit program has a *32 listed after its image name so that you knew directly that it was a 32-bit process.
You can improve that by adding a dedicated platform column to the task manager that reveals right away if a process is 32-bit or 64-bit.
Step 1: First thing you may need to do is click on "more details", as the Task Manager that Windows 10 opens is not usable at all.
Step 2: The processes tab is of no use as well when it comes to determine whether a process is 32-bit or 64-bit. The important *32 addition is missing on that page.
Step 3: Switch to the Details tab. While that offers better information, it still lacks the vital information.
Step 4: Right-click on the title row of the tab and select "select columns".
Step 5: Locate and check "platform" when the new selection window opens.
Platform indicates directly whether a process is 64-bit or 32-bit.
Other means of determining whether a program is 32-bit or 64-bit are not as reliable. While you could look at the installation directory, Program Files (x86) or Program Files, it is not a 100% indicator as programs are not required to install in the right directory.
Also, this does not include any portable program you may be running, or programs that install in other directories by default.
Another indicator that seems to be reliable is to look at a processes compatibility information. Right-click on an executable file on the system or a process in the Task Manager, and select Properties from the context menu.
Third-party programs like Process Explorer may also be used to reveal whether a process is 32-bit or 64-bit.
This works similarly to how it is done in the Task Manager. Right-click on the title row in Process Explorer, select "select columns", and then select "Image Type(64 vs 32-bit) under "Process Image".
Now You: do you care if a program is 64-bit or 32-bit on your system?
Adding the “Platform” column will just let you sort by this.
You already have the information in “Processes” tab, see your Dropbox on your screenshot, it indicates ” (32 bit)” in Name column.
You are right, I have corrected this in the article.
Here’s a printscreen with System Explorer 220.127.116.1156, my OS is Win10 Pro 64-bit:
Most of the programs runs in 32-bit, excepted Networx and Quick Access Popup.
Am I missing something?
System Properties will tell you the Operating system and Bits.
Hold WIN key hit Pause/Break key
A long click on the Orb, click “Control Panel” click “System”
It won’t tell you if a program is 32-bit or 64-bit though, only that the operating system is. Of course, if you run a 32-bit OS then all programs are 32-bit.
I’m to lazy to do all that. i just open my ccleaner as at the top of it, it shows what my comp is
Are you related to justakiwi ? cousin ? :)
I used to have a need to tell whether certain DLL files were x86 or x64 (without executing them). The program dumpbin.exe, distributed with MS Visual Studio, will do that:
C:> type \util\bitness.cmd
@”C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\amd64\dumpbin.exe” /headers %1 |findstr “x86 x64”
C:> bitness [some exe file]
14C machine (x86)
Dumpbin described here: https://msdn.microsoft.com/en-us/library/c1h23y6c.aspx
If you don’t have Visual Studio, dumpbin can be downloaded here: http://originaldll.com/file/dumpbin.exe/39045.html
I care if a program is 64 or 32 bit. I prefer running a 64 bit version of a program if available, except for programs available in 64 or 32 bit that have plugins only written for 32 bit that I wish to use. (Windows 10 x64 Home)
Geek Uninstaller (free) automatically differentiates between 32-bit and 64-bit applications and the list includes all installed programs, not just those which are running at the time.
Revo Uninstaller Pro 3.1.7 (not free) also shows a column for 32 or 64 bit for all installed programs.
And then there is the problem of what to do if the software that you use and like supports right-click context menu entries for 32-bit only, and displays nothing in the 64-bit context menu? What you need, in this case, is WOW64 Menu, a simple 64-bit right-click command that displays the 32-bit context menu and allows you to use it.
I found v18.104.22.168 on Softpedia (the link in the original article did not work):
This solved my problem with dbPowerAmp’s “Convert To” not showing up on the context menu.
You wrote: “All versions of Windows highlight 32-bit processes”. Does that go for Windows 2000, or Windows 95? They didn’t even have 64 bit versions. Nor will 32-bit installs of XP or Vista highlight anything of the kind. You are a fuktard. Thanks for the waste of time.
THANK-YOU!, it really helped
Is there a scanner for all 32 bit.exe files stored into the hard disk?
