Here, “MM/DD/YYYY” represents the month, day, and year of the original Windows installation, while “HH:MM:SS” indicates the time.

Understanding the Command

  • Systeminfo Command:- The `systeminfo` command provides detailed information about the computer’s configuration, including the original install date of the operating system.
  • Findstr Filter:- The `findstr` command filters the output to display only lines containing the specified string, in this case, “Install Date.”

Tips and Considerations

  • System Changes: Keep in mind that if there were any significant changes to the system, such as a reinstallation of Windows, the original install date may not accurately reflect the most recent installation.
  • Scripting and Automation: If you need to extract this information for scripting or automation purposes, consider redirecting the output to a text file for easier parsing.


Discovering the Windows install date through the Command Prompt is a straightforward process, thanks to the `Systeminfo` command and the `findstr` filter. This information can be valuable for various scenarios, such as system maintenance, troubleshooting, or auditing.

By incorporating this command into your regular system checks, you can keep track of important system events and changes over time.
