Windows server last reboot time

Question

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. http://www.windows-commandline.com/windows-last-boot-time/#comment-24721 — Giri, Aug 07 '15 at 04:35

Start → Run → cmd.exe:

systeminfo | find "System Boot Time"

Or for older OS versions (see comment):

systeminfo | find "System Up Time"

Works in Windows XP and I would assume Windows Server 2003, but doesn't work on Windows 2008 as it is now "System Boot Time". – steve.lippert Jul 12 '10 at 14:53

Filter the System Event Log for Event ID 6009.

This is especially nice because if you keep a large enough event log, you will have a history of many previous reboots. – David Jul 12 '10 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.

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

Since the last boot time is for troubleshooting a useful information, we automaticalley display it on every server as background wallpaper

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

Following gives history of shutdown dates.

Refer How to get the list of shutdown event with date?

Filtering the System events with the event id 1074 in Eventvwr.exe helped me
