Thank you very much.

@DaveyK38 , the response from MDH_999 is spot on. The suggestion is to effectively delete any windows update your machine has ever downloaded and then re-download them again. It's basically a clean install of all windows updates. This takes a very long time and will require a large amount of downloading. For some people on slower connections, this can take all day and night. You'll go through a number of long reboots as well.

Here's an article that contains the necessary steps. Scroll down to the "Delete SoftwareDistribution Folder" section and start from there.

One other minor tip if you perform the steps from that article. If you can't delete files in that directory, try restarting your computer and then following the steps to stop Windows Updates. Once you run windows updates, it puts locks on files in that directory.

Does this overwrite the existing installation? Will I have to reinstall programs that I have installed?

thanks

If trying to install the update manually then i have one solution that will work right away.

Although this may seem scary but we are basically hoing to reinstall windows.

what you need to do is download the windows 10 media creation tool from here:

UK

https://www.microsoft.com/en-gb/software-download/windows10

US

https://www.microsoft.com/en-us/software-download/windows10

once downloaded run the installer and you will have 2 options download an ISO etc and "Upgrade this pc".

Even thought you may already have windows 10 what this will do is reinstall windows like if you upgraded from windows 7/8 and in the process will download any updates so when it installs it will have most updates (like the one that is causing you trouble). Just make sure that before you install you make sure the setting (keep my files) which should be automatically enabled is checked. once installed all of your problems should be gone!

NOTE: one thing that is lost will be your desktip background so make sure you have a copy of that

Hope that make sense,

please reply if you have any questions

My experience is that starting the services to auto does not work reliably.

My solution was to uninstall all of the previous updates (except 2 that had no uninstall available).

Following this the Cumulative Update KB4056892 (that for me had failed only 6 times) was no longer attempted and the more recent Cumulative Update KB4090913 was installed instead.

Now my Windows 10 Pro build 1709 shows fully up-to-date.

Think of it like this - it you continuously decorate with more and more coats of paper and paint there comes a time when nothing sticks and you have to strip back to basics!
