How to find out the system capacity Windows 7, 8, 10 – 32 or 64 bits (x32, x64, x86)?

32-64 bits Good hour everyone.

Very often, users ask themselves what bit of the operating system Windows they have on their computer, and what it gives in general.

In fact, for most users there is no difference in the OS version, but you still need to know which one is installed on the computer, since programs and drivers may not work on a system with a different bit depth!

Operating systems starting from Windows XP are divided into 32 and 64 bit versions:

  1. 32 bits are often prefixed with x86 (or x32, which is the same);
  2. 64 bit prefix – x64.

The main difference, which is important for most users, 32 from 64 bit systems is that 32 bit systems do not support more than 3 GB of RAM. Even if the OS shows you 4 GB, then applications running in it will still use no more than 3 GB of memory. Thus, if your PC has 4 or more gigabytes of RAM, then it is advisable to choose the x64 system, if less, install x32.

The rest of the differences are not that important for 'ordinary' users …

How to find out the bitness of the system Windows

The methods below are relevant for OS Windows 7, 8, 10.

Method 1

Press the key combination Win + R, and then type the command dxdiag, press Enter. Relevant for Windows 7, 8, 10 (note: by the way, the line 'execute' in Windows 7 and XP is in the START menu – you can also use it).

Run: dxdiag

Run: dxdiag

By the way, I recommend that you familiarize yourself with the complete list of commands for the Run menu – (there are many interesting things :)).

Next, the DirectX Diagnostic Tool window should open. It provides the following information:

  1. time and date;
  2. computer name;
  3. information about the operating system: version and bitness;
  4. device manufacturers;
  5. computer model, etc. (screenshot below).

Method 2

To do this, go to 'my computer' (note: or 'This computer', depending on your version Windows), right-click anywhere and select the 'properties' tab. See screenshot below.

Properties on my computer

Properties on my computer

You should see information about the installed operating system, its performance index, processor, computer name and other information.

System type

System type: 64-bit operating system.

Opposite the item “system type” you can see the bit depth of your OS.

Method 3

There are special utilities for viewing the characteristics of a computer. One of these is Speccy (you can find more details about it, as well as the download link in the link below).

Several utilities to view computer information –

After starting Speccy, right in the main window with summary information, it will be shown: oOS information Windows (red arrow in the screenshot below), temperature of the CPU, motherboard, hard drives, information about RAM, etc. In general, I recommend having a similar utility on your computer!

Speccy: component temperature, information about Windows, hardware, etc.

Pros and cons of x64, x32 systems:

  1. Many users think that as soon as they install a new OS on x64, the computer will immediately start working 2-3 times faster. In fact, it is almost no different from 32 bit. You will not see any bonuses or cool additions.
  2. x32 (x86) systems only see 3GB of memory, while x64 will see all of your RAM. That is, you can increase the performance of your computer if you previously had an x32 system installed.
  3. Before upgrading to an x64 system, check the manufacturer's website for drivers for it. It is not always possible to find drivers for everything. You can, of course, use drivers from all sorts of 'craftsmen', but the performance of the devices is not guaranteed then …
  4. If you work with rare programs, for example, written especially for you, they may not work on x64 systems. Check them out on a different PC before moving on, or read reviews.
  5. Some x32 applications will work as if nothing had happened in the x64 OS, some will refuse to start or behave unstably.

Should you upgrade to an x64 OS if you have an x32 OS installed?

Quite a common question, especially for novice users. If you have a new PC with a multi-core processor, a large amount of RAM, then it is definitely worth it (by the way, such a computer probably already comes with x64 OS installed).

Earlier, many users noted that more frequent crashes were observed in the x64 OS, the system conflicted with many programs, etc. Today, this is no longer observed, in terms of the stability of the x64 system, it is not much inferior to x32.

If you have a regular office computer with no more than 3 GB of RAM, then you probably shouldn't switch from x32 to x64. In addition to the number in the properties, you will receive nothing.

For those who use a computer to solve a narrow range of tasks and successfully cope with them – they switch to another OS, and indeed change the software – there is no point. For example, I saw in the library computers with 'self-written' bases of books, working under Windows 98. In order to find a book, their capabilities are more than enough (probably, that's why they don't update them :)) …

That's all. Have a great weekend everyone!
