Windows 10 of any version is repeatedly failing to install available updates with error messages and codes that may be different depending on particular update or the stage at which it is failing to install.
Error Message may read like the one I received below:
Windows failed to install the following update with error 0x8007045B: 2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776)
You may also experience that even after an update has finished downloading and requested a restart to complete installation, the update will not install, and will start downloading again. This may go on in endlessly loop of – download, restart, fail to install, and download again!
There are numerous suggestions online to fix this Windows 10 Fall Creator Update 1709 errors, but from personal experience and Feedback from others, most of the suggestions do not work.
Some people were successful with Fix #1 – Windows Updater troubleshooter, described below. I tried it, and initially thought it was successful, but the update error started all over again within hours of trying the fix. It may work for you, so it is a good place to start. But the solution that fully update Windows 10 for me is my Fix #2 – Windows Update Assistant. It took two attempts, and over 12 hours to complete, so be patient if the progress bar seem to be stuck at a percentage.
Fix #1 – Windows Updater troubleshooter – did not work for me
I tried many suggested solutions I could fine online, but none worked for me. I also tried this Microsoft solution, the Windows Updater troubleshooter, and initially thought it resolved the update errors, but alas, it came back a few hours later.
Windows Updater troubleshooter is a free download offered by Microsoft to fix Windows 10, 8 & 7 update problems. You can download and run the troubleshooter specific to your Windows version.
Download the Microsoft Windows Updater Troubleshooter from the link below and make sure you run it as the local administrator of your computer.
Fix #2 – Windows Update Assistant – this Worked for me
Windows Update Assistant is another fix from Microsoft for resolving Windows update issues, and this worked for me. Be prepared to leave your computer on for several hours while the Update Assistant is in progress. It took me two attempts and a restarts of my computer to get the update running successfully, and it took over 12 hours to complete. It may have taken more hours because I left my computer on overnight, and in the morning it was still at 98% complete! And computer is a fairly quick, with Intel i7 processor & 12GB RAM!
This Fix #2 is my recommended solution for resolving Windows update problem and you can download the tool from the link below.
You should see the page below. The download page may change, but that was the Windows Update Assistant Download page when I resolved my Windows problem. Click on Update now to start.
Hope either of these suggested fixes resolves your Windows update problem as it did for me.
