How to Check Your Computer Uptime on Windows 11 and 10

Ever wonder how long your computer has been running without a reboot? Whether you’re troubleshooting performance issues, monitoring system reliability, or just curious, checking your PC’s uptime is a quick and easy task on Windows 11 and 10.

Here’s how to find out exactly how long your system has been up and running.

Method 1: Use Task Manager

This is the fastest way to check your uptime.

1. Right-click the taskbar and select Task Manager, or press Ctrl + Shift + Esc to open it directly.
2. Click on the Performance tab.
3. Select CPU from the left sidebar.
4. Look at the bottom of the window — you’ll see “Up time” listed.

This value shows how long your computer has been powered on since the last restart or boot-up.

Method 2: Use Command Prompt

If you prefer working with commands:

1. Press Windows + R, type cmd, and hit Enter.
2. Type the following command and press Enter: net statistics workstation
3. Look for the line that says “Statistics since…”

That date and time indicate when your computer was last started.

Method 3: Use PowerShell

Power users might want to try PowerShell for a more precise result.

1. Press Windows + X and select Windows PowerShell (or Terminal in Windows 11).
2. Enter this command: (get-date) - (gcim Win32_OperatingSystem).LastBootUpTime

This command calculates the exact duration since your last boot, down to the second.

Why Check Uptime?

Here are a few practical reasons:

• System diagnostics: Helps identify if uptime is contributing to memory leaks or performance slowdowns.
• Update tracking: Useful to confirm if your machine restarted after a Windows update.
• Server monitoring: Uptime is a basic health metric for servers or always-on systems.

Final Tip

If you notice your uptime stretching into weeks or months, it might be time for a restart. Even if everything seems fine, rebooting clears temporary files and resets processes — a simple way to keep your system running smoothly.
