Windows 10 is the latest version of Windows, and it’s available for purchase from Microsoft. If you’re running a computer that’s been built since Windows 8.1, you may be using Windows 8.1 or Windows 8.2. If you’re running a computer that was built before Windows 10 was released, you may be using either of the older versions of Windows. If you’re not sure which version of Windows your computer is running, there are a few ways to test it. One way is to run the System32\drivers\etc\hosts file on your computer and see which IP addresses are listed. If your computer is running the older version of Windows, most likely some of these IP addresses will be listed as well: 192.168.1.* instead of 192.168.2.* . Another way to test whether or not your computer is running the latest version ofWindows is to run the System32\drivers\etc\version file on your computer and see which value has been changed since last time it was run (for example, 10_0_0 instead of 10_0_1 ).

Figuring out whether you’re running a 32-bit or 64-bit version of Windows only takes a couple of steps and the tools are already built into Windows. Here’s how to find out what you’re running.
Whether you’re running 32-bit or 64-bit Windows makes a pretty big difference. Running a 64-bit version of Windows means having better security and the ability to use more memory in your system. And, if you have a system that supports it, making the switch from 32-bit to 64-bit Windows is free—even if it does require a bit of work. We’ll walk you through how to find out whether you’re running a 32-bit or 64-bit version of any version of Windows from XP through 10.

Checking Your Version of Windows 10
To check whether you’re using a 32-bit or 64-bit version of Windows 10, open the Settings app by pressing Windows+i, and then head to System > About. On the right side, look for the “System type” entry. It will show you two pieces of information—whether you’re using a 32-bit or 64-bit operating system and whether you have a 64-bit capable processor.
Checking Your Version of Windows 8
If you’re running Windows 8, head to Control Panel > System. You can also hit Start and search for “system” to find the page quickly. Look for the “System type” entry to see whether your operating system and processor are 32-bit or 64-bit.
Checking Your Version of Windows 7 or Vista
If you’re using Windows 7 or Windows Vista, hit Start, right-click “Computer,” and then choose “Properties.”
On the “System” page, look for the “System type” entry to see whether your operating system is 32-bit or 64-bit. Note that, unlike in Windows 8 and 10, the “System type” entry in Windows 7 does not show whether your hardware is 64-bit capable.
Checking Your Version of Windows XP
There’s almost no point in checking whether you’re using a 64-bit version of Windows XP, because you’re almost definitely running a 32-bit version. Still, you can check by opening the Start menu, right-clicking “My Computer,” and then clicking “Properties.”
In the System Properties window, head to the “General” tab. If you’re running a 32-bit version of Windows it won’t say anything here other than “Microsoft Windows XP.” If you’re running a 64-bit version, it will be indicated on this window.

Checking whether you’re running 32-bit or 64-bit is easy, and follows nearly the same process on any version of Windows. And once you’ve figured it out, you can decide whether you want to use 64-bit or 32-bit apps.
