Uptime since last reboot in Windows 7

If you leave your computer running on a 24/7 basis you might be interested in determining the amount of uptime that has accumulated since the last reboot.

Click empty space on Taskbar to open a menu.

Select Start Task Manager.

Select tab Performance.

At the bottom of the windows you can see Up Time which shows how much time has passed since the last reboot.

You can also check uptime in more geeky method by using Command Line.

Start cmd

Run command systeminfo

Under System Boot Time you can see the date and time when the computer was started.

This command also has more general usage as it also shows a lot of other useful info about our system.
