NirSoft just released another free portable utility called TurnedOnTimesView that displays the information about the time range when your computer was turned on and when it was turned off. Each entry shown in the app displays the following information: Startup Time, Shutdown Time, Duration, Shutdown Reason, Shutdown Type, Shutdown Process, and Shutdown Code.
Just like all other NirSoft tools, TurnedOnTimesView is a portable tool that you can run it without having to install it first. Once it runs, it analyses the system event log of your Windows operating system to get the shutdown, startup time information and displays them in a tabulated layout. It works on any version of Windows, from Windows 2000 and up. Both 32-bit and 64-bit systems are supported.
Normally, it runs without admin privilege but in some cases, in order to get information about the system shutdown caused by a system crash, you will need to run the tool in admin rights, which means right-click on the executable file and choose “Run as Administrator”.
The information TurnedOnTimesView gathered is based on what’s been collected in Event Log. When the computer is turned off improperly, such as caused by a power outage, the tool will not be able to detect the correct shutdown time from the log. And in that case the icon of this entry will be indicated in red, instead of green. As you can see from the screenshot above, I have a lot of improper shutdown activities on my computer. It’s a laptop I am using that doesn’t like to be left on at all time. It often just crashed on me if it was left running overnight.
You can also use TurnedOnTimesView to get the same information from a remote computer in the same LAN. Assume you have the enough rights to read the remote computer’s event log, you can do so by going to Options → Advanced Options, and choose “Remote Computer” as the Data Source, with a computer name typed in below.
If needed, you can also export the information to a file in different formats, plain text, CSV, or HTML. Or, you can copy and paste them into excel spreadsheet as well.
