Knowing the exact version of Windows running on a machine is fundamental for troubleshooting, security updates, and software compatibility. While the graphical interface provides an easy way to check, the command line offers a faster, more precise method for administrators and power users. This guide details the specific commands and switches required to retrieve this information directly from the terminal.
Opening Command Prompt and PowerShell
Before executing version queries, you must first access the command-line interface. Command Prompt is the traditional terminal, while PowerShell offers a more modern scripting environment with enhanced object-oriented output. Both interfaces understand the core commands for displaying system version data, and choosing between them often depends on personal preference or the complexity of the task at hand.
Command Prompt vs PowerShell
To open Command Prompt, press the Windows key, type cmd , and press Enter. For PowerShell, type powershell in the search bar. While Command Prompt provides basic text output, PowerShell can format data into structured tables or lists, making it easier to parse programmatically. Regardless of the terminal used, the primary commands for checking the Windows version remain consistent across both platforms.
Primary Commands for Version Checking
The most direct method to check the Windows version is by using the systeminfo command. This utility retrieves detailed configuration data, including the OS name, build number, and installation date. While it provides a comprehensive report, the output can be verbose for users who only need the version number.

Leveraging the Win32_OperatingSystem Class
For users working within PowerShell, the Get-CimInstance cmdlet provides access to the Windows Management Instrumentation (WMI) database. Specifically, the Win32_OperatingSystem class contains properties that return the version number and build in a structured format. This method is particularly useful for scripting, as the output can be easily stored in variables for further automation.
Querying with PowerShell
Executing (Get-CimInstance -ClassName Win32_OperatingSystem).Caption returns the full name of the OS, such as "Microsoft Windows 11 Pro". To retrieve the specific build number, you can use (Get-CimInstance -ClassName Win32_OperatingSystem).BuildNumber . This granular approach allows administrators to extract only the data points they need, streamlining the process of inventory or compliance checks.
The Quick Version Verifier
When speed is the priority, the ver command offers the fastest interaction. Originally designed for MS-DOS, this command remains compatible with modern Windows systems and returns the kernel version immediately. Although the output is minimal, it provides instant confirmation of the environment without waiting for detailed system scans.
Ver and Alternative Syntax
Typing ver in any command-line interface will display the version string, typically formatted as "Microsoft Windows [Version 10.0.19045.3570]". Some users might also utilize the shorthand echo %OS% or echo %VERSION% ; however, these environment variables often return generic labels like "Windows_NT" rather than the specific build number. For accurate results, relying on ver or the structured commands mentioned previously is recommended.
