How to Find Computer System Uptime on Windows 10

If you leave your computer on for a long time, it is usually a good idea to restart it from time to time. In addition, if you manage multiple computers, it is difficult to remember when everyone has received a reboot. That’s why Windows keeps track of all your operating time and the last time your computer was started for you.

Here’s how to access this information:

Using the Task Manager

The Task Manager is a useful tool that allows you to view all running and launched applications. Although the Task Manager is perfect for monitoring active processes, you can also use it to monitor system performance. With this function, you can monitor the use of your CPU, memory and disk in real time. You can also consult other relevant information such as the availability of your system. To check your availability with the Task Manager, do the following:

  • Press Ctrl + Shift + Esc to start the Task Manager.
  • Once the Task Manager is started, go to the Performance section. In the
  • Performance tab, you will find all kinds of useful information about your CPU, as well as system availability.

Using PowerShell

Open a high PowerShell prompt, type the following, then press Enter :

(get-date) – (gcim Win32_OperatingSystem).LastBootUpTime

You can see the start times in days, hours, minutes, seconds and milliseconds.

Here, you use the Get-Date cmdlet to return the current date and time, then subtract the value of the LastBootUpTime property that comes from the Win32_OperatingSystem, called TechNet. GCIM is an alias for Get-CimInstance.

Use the control panel

Another simple way to determine the uptime of your system is to check the status of your network adapter using these steps:

  1. Open Start.
  2. Locate the Control Panel and click on the top result to open the experience.
  3. Click on Network and Internet.
  4. Click on Network and Share Center.
  5. In the left pane, click Change Adapter Settings.
  6. Double-click on the network adapter connected to the Internet.

Once the steps are completed, you can calculate the availability time of your computer from the duration information, which indicates the availability time of the network connection that is reset each time the device starts (Of course, these methods work as long as you have not reset your network connection since the last time the device started.)

Using the Systeminfo command

  • Select “Start”.
  • Type “cmd”, then press “Enter”.
  • Enter “systeminfo” and press “Enter”.
  • A line entitled “System Boot Time” appears.
