When your PC attempts to download and install new updates for its software applications or operating system, it stores a detailed log of each update. If any of the updates fail to install properly, then they are noted in the "Automatic Updates" history log. There is no direct way to clear this log of failed updates, but you can clear its contents by manually deleting the update data.
