When was Windows 10 or Windows 11 installed?

There are times when you want to know the date and time when Windows 10 or Windows 11 was installed on a computer.

There are a few ways to determine the date and time Windows was installed on a computer. To find out how old a computer is or if Windows has been reinstalled, check the installation date.

One thing you need to know: the installation date will not always be accurate. That's because, if you upgraded to a newer version of Windows (for example, upgrading from Windows 10 to Windows 11), the original installation date shown is the date of the upgrade.

How do you know the date Windows was installed?

To find out how old your computer is, check the Windows installation date. It will tell you when Windows was installed or upgraded to a new version.

Click on the start button. In the search window type: Command Prompt. Right-click on the Command Prompt result and click “Run as Administrator”.

In the Command Prompt, type the following command:

systeminfo | find /i "original"

You will now see the “Original Install date” and a time. This is the Windows installation date or the date Windows was updated to a new version.
