$os = Get-WmiObject win32_operatingsystem
$uptime = (Get-Date) - ($os.ConvertToDateTime($os.lastbootuptime))
$Display = "Uptime: " + $Uptime.Days + " days, " + $Uptime.Hours + " hours, " + $Uptime.Minutes + " minutes"
Write-Output $Display

太冷清.贴个源函数实现方法

Function GettickCount(){
$t=Add-Type -MemberDefinition @'
[DllImport("kernel32")]
public static extern int GetTickCount();  
'@ -passthru -name SystemTickTime
    Return $t::GetTickCount()
}
[string]$s=[regex]'(\d+)\..+|\d+'
[int]$t=(GetTickCount)
[string[]]$r=($t/1000/86400),($t/1000/3600),($t/1000/60%60),($t/1000%60) -replace $s,'$1'
$r[0]+'天'+$r[1]+'时'+$r[2]+'分'+$r[3]+'秒'

两个都不能运行，提示：

无法加载文件 .。。。。。，因为在此系统上禁止运行脚本。
+ CategoryInfo          : SecurityError: (:) []，ParentContainsErrorRecordException
+ FullyQualifiedErrorId : UnauthorizedAccess

原来要先Set-ExecutionPolicy RemoteSigned
已解决这错误提示。

这个可行：

[Timespan]::FromMilliseconds([Environment]::TickCount)
