How to find out uptime on Windows?

"Run command line
Type Systeminfo
Find ""System Boot Time""

Days: 10 Hours: 10 Minutes: 10 Seconds: 10

For shorter result you can use:

systeminfo | find ""Boot Time"""

"Open the command prompt and type:

net stats srv | find ""Statistics""

Example output:

>net stats srv | find ""Statistics""
Server Statistics for \\4IFS-SANDER
Statistics since 22/07/2009 10:14:14

Source (MS KB).

Edit: Actually this will tell you the date and time when the pc was up from, not the duration."

"If you have the Windows Server 2000 or 2003 resource kits try

srvinfo -ns [\\\server] | Findstr ""Time""

Note: Srvinfo.exe will not run on a 64-bit versions of Windows, due to it being 16-bit."

"Using SYSTEMINFO with PowerShell

For those who like using PowerShell, you can use the answer(s) above and wrap systeminfo in a PowerShell function to get a DateTime result for when the server last booted:

function Get-ComputerBootTime {
param($ComputerName = (hostname))

$SystemInfo = & systeminfo /s $ComputerName | Select-String ""System Boot Time"")
if($SystemInfo -match ""[\d/]+,\s+\S+""){
return (Get-Date $matches[0])
}
}

And then call the function, for example:

[PS]> $BootTime = Get-ComputerUptime -ComputerName MYSERVER

To get the Uptime for the server, you compare with the current time:

[PS]> $UpTime = (Get-Date) - $BootTime

This is a TimeSpan, which includes properties such as TotalDays:

[PS]> $UpTime.TotalDays
14.1827364"

"Yet another way:
C:\>wmic path Win32_OperatingSystem get LastBootUpTime
LastBootUpTime
20200908203723.500000+120"
