Knowing the system uptime is a useful piece of information. In Windows Server 2008 there are two easy methods of displaying this information.
Using the Task Manager
1. Right-click on the Taskbar, and click Task Manager. You can also click CTRL+SHIFT+ESC to get to the Task Manager.
2. In Task Manager, select the Performance tab.
3. The current system uptime is shown under System.
By Using the System Information Utility
Probably one of the easiest methods to accomplish this task. The Systeminfo command line utility checks and displays various system statistics such as installation date, installed hotfixes and more.
Open a Command Prompt and type the following command:
systeminfo
You can also narrow down the results to just the line you need:
systeminfo | find "System Boot Time:"
