Windows 10 LastBootUpTime not updating

Question

_{Saturday, October 3, 2015 12:30 PM}

Since I installed Windows 10 on my PC, the value for LastBootUpTime has not updated.

I use BGINFO to display system info and the "Boot Time" value has not changed. I have gone so far as to perform a system shutdown and removing power from the PC, but nothing helps.

I have also tried extracting the LastBootTime class property from the "Win32_OperatingSystem" WMI Class, and it shows the same value that "Boot Time" displays.

Is there some system setting that I need to adjust?

Found it! By chance, after my last post here, I search for "PC not fully shutting down" and found my solution...

Because I had the "Turn on fast startup" option enabled in Control Panel\All Control Panel Items\Power Options\System Settings, my pc was indeed not fully shutting down. I turned that option off and boot time is now showing correctly in BGInfo and the others.

Now, I need to decide what is more important - FAST BOOTS and slight power savings or accurate statistics!

System Boot Time displays fine for me so it appears to work on Windows 10. Just checked BGinfo and that shows my last boot time.

if you type systeminfo from a command prompt does that show the System Boot Time you are expecting?  (quite a lot of info System Boot Time about 11 lines from the top)

Is the time ok on your PC? is that correct does it update, any settings been changed in time related settings?

Systeminfo returns the same time as LastBootTime and BGinfo.

Interestingly, shortly after I posted my original question, I performed a Windows Update, and when it rebooted to PC, the LastBootTime showed up properly. Now, it's showing THAT time (10/3/2015 09:14), even after a fresh power-up this morning (10/4/2015).

Ah, yes, my system time is accurate, and I have not made any time-related changes to my system.

Odd, almost like it does not get triggered or does not have permission to set it.

In the System event log, at boot time there is a Event ID 12 source Kernel-General, is that present? are there any errors at the same time?

Is that event the same on the reboot after the Windows updates that set the last boot time and the normal reboots that do not? (thinking the User listed or something)

Sorry it took a while to get back on this one.  I took a look in the system event log and the latest Event 12 was on the same date, a couple of seconds before the time shown with BGInfo, but the same time as shown in LastBootUpTime and SystemInfo.

I'm going to perform a test in a few minutes. I'll be leaving the house for a couple hours, I will shot down and unplug power from the PC to see if it changes when I return.  (I have noticed that the shutdown behavior has changed since I installed W10 - the PC reboots with keyboard input now, so I wonder if it is not truly shutting down)

Great!! thank you, I had the same problem. Now I prefer disable the Fast Boot option, for me the accurate statistics are more important.

Just a little aclaration, I was looking the "Power Options/System Settings" entry, but I never found where to do click :)   and the trick was do click in the "Require a password on wakeup" option in the left side of the window. Inside is the checkbox "Turn on fast startup (recommended)" unchecking the checkbox the problem goes out.

Resolved the same problem for me.

Thanks.
