Windows 10: How long does the 1903 upgrade take using Windows Update?

Short answer - a very long time.

I had reason to take my System One below back to an earlier system image and upgrade it to 1903 again. In fact, the image I restored for this machine was its 1511 image from mid-2016. I then upgraded this to 1809 using an ISO in about two hours.

Just for fun (?) I decided to let Windows Update perform the Feature Update to version 1903. Now this machine had previously been updated from 1809 to 1903 using an ISO, so I knew that method took no more than a couple of hours. How much longer could Windows Update take?

Well, it would be expected to to take a little longer, because it uses the Unified Update Platform (UUP). This is designed to reduce the download size of an update by only downloading the changes, not the full set of files as are used in the ISO.

So, the download is smaller, but there's more work to do with it after downloading. I told Window Update to 'Download and install now', set the stopwatch going and opened Task Manager to watch what was going on.

The first step was Windows Update saying "Getting ready". This stage took 15 minutes to complete, then the download began.

Windows Update said "Downloading - 0%" which climbed steadily to 99% while Task Manager showed steady download progress. Network activity virtually ceased after 3.5GB had been downloaded in 15 minutes (this time is entirely dependent on your broadband speed).

The step from "Downloading - 99%" to "Downloading - 100%" took an astonishing 42 minutes, during which there was little or no network activity but a lot of CPU activity, mostly from the Windows Installer. This would presumably be the stage.

Then Windows Update first said "Pending install" then quickly switched to "Installing - 0%"....


....Paint would have dried quicker - it took a further three hours and ten minutes to get to "Installing - 100%" and asking me to select a restart time to complete the install.

Then, on the restart, it rejoined the same steps of 'installing updates' and restarts that an ISO upgrade would have followed, taking a further 40 minutes.


So, in conclusion what would take less than two hours with an ISO (I know, because I have previously used the 1903 ISO on this machine) took over four and a half hours via Window Update. I can't say I'm that impressed. At least it worked reliably, I'll give it that. And I suppose I could have continued using the machine while the update ground away in the background (I didn't though, I went out for an hour or so instead). At least I now sport a nice entry in the Update History.....

Hi roblinb

Not listed in the Known.

As far as Wifi any chance it is Qualcom inside USB adapter, if Qualcom then yes known issue.


I might create another user (Local) and when if try again see if this issue occurs on both users.

Would also suggest you run the first 5 steps in this tutorial to see if you have any corruption with current build.

Windows 10, version 1903 update failure

Hmm, this is Windows 10 1809 which is the most recent release which is now being succeeded by Windows 10 1903.

I would carry out the steps from my initial reply to reset your Windows Update components.

Also review the following:

Have you checked the manufacturers website to determine compatibility?

Your configuration might not be listed yet, since it is just rolling out.

Ultimately, I would wait until the ISO file is available then upgrade offline using these steps:

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.
