How to Identify the Operating System Version on Linux and Windows

Knowing the version of your operating system can be essential for troubleshooting, compatibility checks, or software installation. This guide walks you through how to check your OS version on both Linux and Windows systems using straightforward methods.

Checking OS Version on Linux

Linux offers multiple ways to find detailed information about the operating system version. Here are some simple methods:

1. Using the lsb_release Command

The lsb_release command provides a clean and concise output for your Linux distribution details. Run the following in the terminal:

lsb_release -a

This will display information like the distributor ID, release version, and codename.

2. Inspecting the /etc/os-release File

Many modern Linux distributions include an os-release file that contains OS-related metadata. View its contents with:

cat /etc/os-release

Look for fields such as PRETTY_NAME or VERSION_ID for a quick glance at your OS version.

3. Checking the Kernel Version

To determine the kernel version, use:

uname -r

This command will display the current kernel version, which can provide additional insights about your system.

4. Using the hostnamectl Command

On systems with systemd, hostnamectl can provide a summary of your OS and hardware. Execute:

hostnamectl

Look for the "Operating System" field for detailed OS version information.

Checking OS Version on Windows

On Windows, you can find the operating system version using either graphical tools or command-line utilities.

1. Using System Properties

• Press Win + R to open the Run dialog.
• Type control and hit Enter to open the Control Panel.
• Navigate to System and Security > System.

The window will display your Windows edition, version, and system type (32-bit or 64-bit).

2. Using Command Prompt

Open Command Prompt and type:

ver

This will display the Windows version. For more detailed information, use:

systeminfo

This command provides a comprehensive report, including the OS build number and installation date.

3. Using PowerShell

Open PowerShell and run:

Get-ComputerInfo | Select-Object WindowsVersion, WindowsBuildLabEx

This provides a detailed overview of your Windows version, build, and other relevant details.

4. Using the Settings App

• Press Win + I to open the Settings app.
• Go to System > About.

Under "Windows Specifications," you’ll find the version and build number of your OS.

Why Knowing Your OS Version Matters

Identifying your operating system version is crucial in various scenarios:

• Ensuring compatibility with software or hardware.
• Troubleshooting issues that are specific to certain OS versions.
• Keeping your system secure by verifying it’s up to date.

With these simple steps, you can quickly check your OS version on both Linux and Windows. Whether you're a beginner or a seasoned user, these methods ensure you have the information you need at your fingertips.
