If you have ever been curious about when you installed Windows 10 on your system, find out when the OS came to be for you using these simple commands!


Calendar dates have always been an important part of our lives. Whether it’s birthdays, anniversaries, or even just your Monday blues, it is always good to know important dates.

If you are the kind of computer user who is big on celebrating their OS lasting more than a year, find out when your OSVersary is by using these simple commands in command prompt (cmd) or Powershell to find out the date and time when Windows 10 entered your system.

To do so, you simply need to run Windows Key + R to bring up the Run screen. From here, we can use Command Prompt or Powershell to identify the date and time Windows 10 was installed on your system.

Find Install Date Using Command Prompt

If you want to use the command prompt, you simply need to press Windows Key + R and type in cmd.

When you see the screen, you can just copy and paste the following code. You could obviously type it out if you know how to type the vertical bar “|” (you can do it by pressing Shift + backslash key). Do ensure you include the quotation mark ” at the end – it is not a typo.

When you have typed out the command below, execute it by pressing the Enter key.

After a few seconds, you will have the following output.

Check Install Date Using PowerShell

There’s another method if you prefer using PowerShell.

Once again, bring up the Run screen with the help of Windows Key + R and type in Powershell.

Wait for the program to load, and then type in the following command or copy / paste it. When you have done so, execute the command again by pressing the Enter key.

([WMI]'').ConvertToDateTime((Get-WmiObject Win32_OperatingSystem).InstallDate)

You should now see the following output:

Output in Powershell.

You can see that the output values are more or less consistent but the date format is a distinct difference between the two programs. The install date and time is a bit more readable on PowerShell.

With this knowledge in hand, you should now be able to see and determine how old is your OS installation.

If you are the kind of person who appreciates milestones and installed Windows 10 when it came out, chances are you are about to reach the one-year anniversary of Windows 10 being installed on your system!

Windows 10 was released July 29th, 2015 globally and while a majority of the people didn’t get to install the OS until a few days later due to whatever reason, you might want to plan ahead for your first OSVersary! 😉

In addition, the output tells you the date Windows 10 booted on your system. So this data is for people who upgraded to Windows 10 from Windows 7 / 8 / 8.1 or even directly installed the OS from a media.
