Is there a way to determine the 'uptime' of a process in Windows. Disappointed to find that it is not one of the attributes available when using the Task Manager.

You can see this with Process Explorer. In the taskbar menu select View and check Show Process Tree and the Show Lower Pane options. Right click on any column and Select Columns, now click on the Process Performance tab and check the Start Time box.

Hey TiZon. This looks a really useful tool. Thanks – nick May 12 '11 at 10:12

If you're on a server where you cannot install any external tool, you still can :

  1. Open the task manager
  2. Click on the process tab
  3. Locate your process
  4. Right click on it
  5. Select the Properties option

You can see a "creation date" right there, which should be the creation date of your process. With a simple substraction you can deduce the uptime.

This only works on Windows 8. If you are still on Windows 7, the Properties option shows properties of the running executable file, not of the process. – Klitos Kyriacou Mar 12 '15 at 12:28
Win 8.1 also shows executable file properties – Fck May 29 '15 at 11:54

This can be done using Powershell.

Run it as admin and then execute

Get-Process | select name, starttime

You will get a list of all running processes and their start times
