How can I find a Windows server's last reboot time, apart from 'net statistics server/workstation'?

In fact, net statistics does not seem to be showing the system boot time. windows-commandline.com/windows-last-boot-time/#comment-24721– GiriAug 7, 2015 at 4:35

see also superuser.com/a/909172/33303 if you are interested in other acpi states like hibernation and standby– Janus TroelsenNov 17, 2016 at 12:40

Start → Run → cmd.exe
:
systeminfo | find "System Boot Time"
Or for older OS versions (see comment):
systeminfo | find "System Up Time"

9Works in Windows XP and I would assume Windows Server 2003, but doesn't work on Windows 2008 as it is now "System Boot Time". Jul 12, 2010 at 14:53

This only works with English locale, see @user47994 for a language independent solution– ooxiJul 6, 2015 at 8:22

Filter the System Event Log for Event ID 6009.

4This is especially nice because if you keep a large enough event log, you will have a history of many previous reboots.– DavidJul 12, 2010 at 14:48
open up the powershell command and run this to see all your history ... and no UI necessary :-)
get-eventlog System | where-object {$_.EventID -eq "6005"} | sort -desc TimeGenerated
I use the PsInfo utility from Microsoft's Sysinternals package, which will give you output like this:

If you are using Server 2008, you can see the system uptime in hours on the "Task Manager" - "Performance" tab. As far as I know, the "net statistics ..." way is the only true way on Windows 2003.
Using a wmi client.
C:\>wmic OS GET CSName,LastBootUpTime
CSName LastBootUpTime
SERVER 20101124084714.500000-360
Note: -360 = GMT-6
Last Time the System Booted
My personal favorite is to use WMI and Win32_OperatingSystem properties/methods. Here it is as an easy copy/paste one liner:
((Get-WmiObject Win32_OperatingSystem).ConvertToDateTime((Get-WmiObject Win32_OperatingSystem).LastBootUpTime))
Same thing, but easier for manual typing:
$obj = Get-WmiObject Win32_OperatingSystem
$obj.ConvertToDateTime($obj.LastBootUpTime)
Both options provide output like:
Monday, June 30, 2014 11:59:50 AM
Length of System Up Time
If you want to find out how long the system has been online you can do this (this is also an alternate code style):
$Obj = Get-WmiObject -Class Win32_OperatingSystem
$Obj.ConvertToDateTime($Obj.LocalDateTime) - $Obj.ConvertToDateTime($Obj.LastBootUpTime)
Which gives output like:
Days : 7
Hours : 1
Minutes : 59
Seconds : 42
Milliseconds : 745
Ticks : 6119827457690
TotalDays : 7.08313363158565
TotalHours : 169.995207158056
TotalMinutes : 10199.7124294833
TotalSeconds : 611982.745769
TotalMilliseconds : 611982745.769
Using Powershell
Get-CimInstance -ClassName win32_operatingsystem | select csname, lastbootuptime
CSName LastBootUpTime
Server 7/5/2014 6:00:00 AM
You can easily open your task manager in performance tab under System find your "UpTime"!!!
Since the last boot time is for troubleshooting a useful information, we automaticalley display it on every server

Howto
- Using Bginfo (Microsoft / Sysinternals)
- Configure the wanted information
- Run as scheduled task:
- command line:
Bginfo64.exe /silent /nolicprompt /timer:0
- trigger: on every user logon
- command line:
Following gives history of shutdown dates.
