Uptime in computing refers to the amount of time a computer system has been running without interruption. It is an important metric for system administrators and users alike, as it can provide insights into the stability and reliability of a system.
There are many ways to check uptime in Vista, but the most common is to use the Task Manager. To do this, press Ctrl+Alt+Del and select Task Manager from the menu. In the Task Manager, click on the Performance tab and then select CPU from the left-hand menu. The uptime will be displayed in the CPU Usage History graph.
