Remove Failed Update KB (2345678) Error From Windows Update History [How To]

Windows Update is Microsoft’s own system to push updates to every computer running a version of the Windows operating system, whenever bugs are found and fixes for them are released. The user can choose whether to receive Windows Updates and install them automatically or just to be informed of their availability, for a manual download later on.
The Windows Update system is obviously available in the upcoming Windows 8 but it looks like Microsoft did not make significant changes to the system. This is probably due to the fact that in Windows 7, Windows Update performed very well.
Even if there were no issues with the system in Windows 7, sometimes updates that are pushed through Windows Update fail to install and you end up with a Failed Update error message in the Windows 8 Update history. The updates fail to install due to issues with your operating system, due to no internet connection while the update downloads and so on.
This is why we thought that a guide on how to remove the failed update KB error message from the Windows Update history will be useful to you.
Our first recommendation to you in such a case would be to force the update to be downloaded again. If you do not succeed on your second try, then you can proceed with the Windows Update Regenerator application that we are going to describe in this “How to remove failed update KB error message from Windows Update history” guide.

The application called Windows Update Regenerator will scan your Windows 8 Update list and then remove the failed update KB entries from the update history list. What it actually does, is to regenerate (or recreate) the Windows 8 update list without the updates that failed to install in your Windows, by removing them completely.
In order to start removing failed update KB error messages from the Windows Update history you will have to run Windows Update Regenerator and once you read the application description, press the 1 key to start the update regeneration process.
Please note that your computer will restart once the application finishes the removal of failed update KB errors from the history list. Once done, you will not be able to download the failed updates that were removed from the list but it will be possible to keep on downloading future Windows updates. You will have to start the Windows Update process manually for the first time, in order to check for new updates.
If you want to know the commands that Windows Update Regenerator is using to remove failed update KB error from your Windows Update history list, here is what the developer mentioned on the Win-lite.de board:

net stop Wuauserv
attrib -r %systemroot%\SoftwareDistribution /S /D
rd /s /Q %systemroot%\SoftwareDistribution
net start Wuauserv
shutdown -r
