Checking the uptime on a Windows 11 computer is a straightforward process. It involves using either the Task Manager, Command Prompt, or PowerShell. By following a few simple steps, you can quickly find out how long your system has been running since its last reboot.
How to Check Uptime in Windows 11
In this section, you’ll learn three different methods to check the uptime of your Windows 11 computer. Each method is simple and can be completed in just a few steps. Knowing your system’s uptime helps diagnose issues and monitor performance effectively.
Step 1: Open Task Manager
To begin, press Ctrl + Shift + Esc to open Task Manager.
Task Manager is a built-in Windows tool that provides various details about your system’s performance. Once opened, it gives immediate access to several metrics, including uptime.
Step 2: Navigate to the Performance Tab
Next, click on the "Performance" tab within Task Manager.
The Performance tab displays detailed information about your CPU, memory, disk, and network usage. This tab is where you’ll find the system uptime.
Step 3: Locate the Uptime Information
Look for the uptime information under the CPU section.
In the CPU section, you will see a label called "Uptime." This shows how long your system has been running in days, hours, and minutes.
Step 4: Open Command Prompt
Alternatively, press Windows + R, type "cmd," and hit Enter to open Command Prompt.
Command Prompt is another versatile tool for accessing various system information, including uptime.
Step 5: Enter the Command
Type "systeminfo" and press Enter.
This command provides a summary of your system details. Among these details, you will find the system uptime.
Step 6: Use PowerShell (Optional)
Lastly, you can use PowerShell by pressing Windows + X and selecting "Windows PowerShell."
PowerShell is a powerful scripting tool that also allows you to check system uptime.
Step 7: Type the Uptime Command
In PowerShell, type "(get-date) – (gcim Win32_OperatingSystem).LastBootUpTime" and press Enter.
This command calculates and displays the exact duration since the last boot, providing a precise uptime reading.
Once you’ve completed these steps, you’ll know exactly how long your Windows 11 system has been running. This information can be useful for troubleshooting performance issues or ensuring your system is running smoothly.
