Windows: Uptime Command – CMD & PowerShell

Even though there is still no built-in Windows uptime command, the actual uptime of the server/workstation or the system boot time can be checked from the command-line.

In this note i will show several methods of how to check Windows uptime from the command-line prompt and PowerShell.

Windows Uptime Command

PowerShell vs. CMD: Each of the commands below works both from the command-line prompt (CMD) and PowerShell.

Windows uptime can be checked using the wmic command:

C:\> wmic os get lastbootuptime

Another method to check Windows uptime from the command-line prompt is by getting the system boot time from the output of the systeminfo command:

C:\> systeminfo
- or -
C:\> systeminfo | find "System Boot Time:"

Also uptime of the Windows server/workstation can be checked using the net statistics command that returns the date and time since the statistics has been running, that approximately corresponds to the Windows boot time.

Windows server uptime:

C:\> net statistics server 
- or -
C:\> net statistics server | find "Statistics since"

Windows workstation uptime:

C:\> net statistics workstation
- or -
C:\> net statistics workstation | find "Statistics since"
