Windows查看系统启动时长 uptime.exe

一、通过系统命令

cmd：

dir /ah /tw c:\pagefile.sys|findstr .sys

chcp 437
systeminfo | find "System Boot Time:"
systeminfo | findstr /C:"System Boot Time:"

chcp 437
net statistics workstation | find "since"
net stats work | find "since"
2008R2也可以执行net stats srv| find "since"

cmd wmic：

wmic OS GET CSName,LastBootUpTime

powershell：

cmd.exe /c dir /ah /tw c:\pagefile.sys|findstr .sys

Get-CimInstance -ClassName win32_operatingsystem | select csname, lastbootuptime

(gcim Win32_OperatingSystem).LastBootUpTime
(gwmi win32_operatingSystem).lastbootuptime

get-date
(get-date) - (gcim Win32_OperatingSystem).LastBootUpTime

((Get-WmiObject Win32_OperatingSystem).ConvertToDateTime((Get-WmiObject Win32_OperatingSystem).LastBootUpTime))

$obj = Get-WmiObject Win32_OperatingSystem
$obj.ConvertToDateTime($obj.LastBootUpTime)

$operatingSystem = Get-WmiObject Win32_OperatingSystem
"$((Get-Date) - ([Management.ManagementDateTimeConverter]::ToDateTime($operatingSystem.LastBootUpTime)))"

function Get-SystemUptime {
    $operatingSystem = Get-WmiObject Win32_OperatingSystem
    "$((Get-Date) - ([Management.ManagementDateTimeConverter]::ToDateTime($operatingSystem.LastBootUpTime)))"
}
Get-SystemUptime

powershell专用命令：

Get-Uptime
Get-Uptime -Since

The Get-Uptime cmdlet was introduced in PowerShell 6.0.

uptime123.zip

压缩包里有微软1.0.0.1版本、codeplex uptime1.1版本以及https://neosmart.net/uptime/ 的uptime

四、通过事件ID6005的时间点

get-eventlog System | where-object {$_.EventID -eq "6005"} | sort -desc TimeGenerated
Get-WinEvent -ProviderName eventlog | Where-Object {$_.Id -eq 6005 -or $_.Id -eq 6006}

五、通过sysinternals工具psinfo

psinfo.exe -accepteula -nobanner uptime

六、powershell7特有命令

注意：2008R2不支持powershell7（虽然能安装上，但是执行报错）
