    How to Clear All Event Logs in Event Viewer in Windows


    Event Viewer is a tool that displays detailed information as event logs about significant events on your PC.

    Event logs are special files that record significant events on your PC, such as when a user signs in to the PC or when a app encounters an error. Whenever these types of events occur, Windows records the event in an event log that you can read by using Event Viewer.

    Advanced users might find the details in event logs helpful when troubleshooting problems with Windows and other apps. However, you may also wish to be able to quickly clear all event logs at once as needed.

    This will not clear Analytic or Debug logs. If you have them enabled, the wevutl command returns an error, but all other logs will be cleared.

    Clearing all Event Viewer logs will also clear Reliability History.

    Thank you very much, Brink, for this new tutorial! :)

    I will present the results after applying the commands on my system.

    First of all, it has indeed cleared my Event Viewer logs:

    Clear All Event Logs in Event Viewer in Windows-1.png

    I used the command in CMD, which by the way I have been always using (I mean, even on Windows 7). It works fine! There was only one issue in my Windows 10 Pro, though:

    Clear All Event Logs in Event Viewer in Windows-2.png

    I have no idea what this "AirSpaceChannel" is... I have seen this error in my system other times, as well. I am always using a wired LAN Internet connection. Can you please tell me what is this?


    Then I run the command from the PowerShell:
    Clear All Event Logs in Event Viewer in Windows-3.png

    I think the results were expected, right?
    I just don't understand what the last failure is, the one about the USBvideo/Analytic... Is that expected, too?

    So, thanks Brink! :)

    I am REALLY-REALLY looking forward for a tutorial on how to clear the Reliability History :)

    For Windows logs and Application and Services logs, there is also the manual way to clear specific logs(only these 2 sections, custom views can be Deleted and lost, but not Cleared for example:

    Hey Joanne,

    Yeah, I have no idea what "AirSpaceChannel" is for either.

    That would be normal in Powershell for any of the Analytic or Debug logs.

    Why is it that as the admin I still have to run the bat as admin for it to work; just wondering since on win 7 I just run it as is and it clears all logs. Tried this and would not clear without running using the "run as administrator". Thanks

    Hello csmdew, and welcome to Ten Forums. :)

    It just needs to have elevated rights to be able to clear the event logs from the system.

    Office 2016 includes the AirSpaceChannel


    It's Office 2016.

    Microsoft Office 2016 - AirSpaceChannel
    office 2016 airspacechannel - Google Search

    I know this is an older thread. Regardless, I wanted to post a note here just in case anyone else looks here as I did.

    Just FYI.

    Shawn, thanks a lot for the script.
    One more excellent job (like the life saver I just did with the Restore_Windows_Photo_Viewer one!!!).
    This one seems to be working perfectly, except from one thing, which I have highlighted in the picture.
    Do you have any idea what it is and how it can be fixed?

    Hello Dimitri, :)

    You might see if it may be able to clear it while running it in Safe Mode.
