Hey

Try to apply the update manually As suggested by Microsoft. I just wrote a

However be sure that the update itself is downloaded and that the installation part is failing, and not the downloading part.

Windows Update multiple Install errors/Failure (error 0x80070643)


Hi All,

I'm wondering if anyone can help.

I have upgraded to windows 10 for a few weeks now and over the last couple of days it has stopped installing any windows updates, the error code that pops up is (error 0x80070643)

It's also stopping me from installing some other programs but not all.

I have tried restarting the computer, Nothing
I've tried restarting wuauserv service, Nothing
I've tried the troubleshooter for windows update, it says problems were found and they were fixed.
I have also cleared the cache for update downloads from the following folder:
C:\Windows\SoftwareDistribution\Download

In the Windows update page it seems to take forever to install the updates and then throws out the following:
There were problems installing some updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help:
Security Update for Microsoft ASP.NET MVC 4.0 (KB2993928) - Error 0x80070643

Update for Microsoft Visual Studio 2010 Tools for Office Runtime (KB3001652) - Error 0x80070643

Note: this is after clearing the cache in the above folder location.

If anyone can help that will be great as it seems to be affecting installation of other programs.
