This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Command prompt

  1. Open a command prompt.
  2. Type or paste the following command, and press Enter:

    wmic os get installdate


  • Works regardless of the system locale.

  • The value is in is displayed in the UTC format and is not affected by changes in time zone or daylight saving time.

Example output


The format is yyyyMMddHHmmss. Anything after the period represents the number of milliseconds, which can be safely ignored. The value is parsed this way:

  • 2014 year
  • 05 month
  • 19 day
  • 22 hour
  • 47 minutes
  • 31 seconds


Assuming it's available, you can run the following commands:

$os = Get-WmiObject Win32_OperatingSystem

Example output

it is a bit difficult to read. – Devid May 19 '14 at 23:02
@Devid Added further information, and an alternate solution. – and31415 May 19 '14 at 23:51
Yep, I seen it so I gave +1 – Devid May 19 '14 at 23:52

Start the command prompt (Win+R -> "cmd" -> press return)
Enter the following command:

cmd /k systeminfo | find "Original Install Date"

P.S. I found the information here.

EDIT: The following PowerShell command works for Windows installations with locales other than English.

Start PowerShell (Win+R -> "powershell" -> press return)
Enter the following command:

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

P.S. I got the info from here.

For windows 7 Press Win+R or click start and then run

type cmd and press enter to start command prompt. Inside command prompt, type

systeminfo | find "Install Date"

and press enter, after a few seconds, you should get install date.

For Windows XP it's simpler, simply go to C: and right click on WINDOWS folder and select properties, and look at date the folder was created.

The command won't work on non-English systems. – and31415 May 19 '14 at 23:24
