If you’ve ever wondered just how long your PC has been continuously running without a reboot and you are using Windows NT, 2000, XP, Vista or 7, there are a couple of simple ways to obtain this information using tools built right into the OS.
Method 1: Windows NT/2000 and XP
Open up the command prompt (Start > Run > cmd > Enter/Ok). When the command prompt has loaded type “net stats srv” (or “net statistics server”). NT4 users (are there any, really?) need to download a special utility instead.
Method 2: Windows XP and beyond
Alternatively, you can use the command prompt to obtain system information, type “system info” which will also provide you with your PC’s uptime.
Method 3: Windows Vista and beyond
For those on Vista or Windows 7, things are a little easier (although the above will work just fine). Right click the taskbar and choose “Task Manager” or “Start Task Manager”. Head over to the “Performance” tab and on the bottom right of the window you ought to see your system uptime.
Feel free to share your current uptime in the comments below. Mine right now is at 47 hours, 51 minutes on Vista x64.
