Whether it’s your personal PC or a server, it’s helpful to know how long your system has been running. Here’s how to find your system’s uptime.
In Windows 7 or Vista, right-click an empty area on the taskbar and click Start Task Manager.
Alternately, click Start and type: taskmgr.exe into the search box and hit Enter.
Windows Task Manager launches. Click the Performance tab. Under System you’ll see Up Time. This is how long your computer has been on since the last restart.
In this example, my Windows 7 desktop has been up for almost eight hours.
For Windows Home Server, XP or Server 2003, go to Start >> Run and type: cmd then hit Enter.
At the command prompt type: net stats srv then hit Enter. You’ll see the line Statistics Since – this shows the date and time that your system has been running.
This example is from my Windows Home Server. Quite the difference.
Finding the uptime of your system is a good indicator of when it’s time for a reboot.
