If you want to know how long your Windows computer has been running, you can easily find your System Uptime. Uptime is a term used for referring to the time your computer has been running continuously without a reboot. This post will show you how to find System Uptime in Windows 10/8.1/7/Server, using CMD, SystemInfo command, PowerShell, Task Manager.
Find Windows System Uptime
1] Using PowerShell
Open an elevated PowerShell prompt, type the following and hit Enter:
(get-date) - (gcim Win32_OperatingSystem).LastBootUpTime
You will see the Boot up times in days, hours, minutes, seconds and milliseconds.
Here, you are using the Get-Date cmdlet to return the current date and time, and then subtracting the value of the LastBootUpTime property that comes from the Win32_OperatingSystem, says TechNet. GCIM is an alias for Get-CimInstance.
If you want to find out the Server Statistics, you can open an elevated CMD type the following and hit Enter:
net stats srv
The first line ‘Statistics since‘ will show you the Windows uptime.
3] Using Task Manager
If you open Task Manager, under the Performance tab, you will see your computer Up time displayed there.
