Update to Windows 10 version 1903 stuck at 48%

I needed to update the bios so I could install an i7 9700K, because the board was engineered originally for the 8th Gen. I used the AI 3 Suite to upgrade my motherboard. With the fresh updated bios and adding the i7 9700k, I also used the Intel Update Assistant and also downloaded and installed all the updates for the ASUS motherboard support. After this was all said and done there was no issues updating to the 1903 build. I  can't say what exactly fixed the issue. I suggest making sure your bios is up to date and the Intel Chipset & ME and specter/zombie mitigations are done first. Make sure you don't have any unnecessary startup programs. I wish you the best of luck if you can't just put a new processor in there.

Hi I have a customer's Acer Aspire E1-572G laptop that crashed overnight doing the 1903 update. So I took it back to try to do it for her since she needs the laptop for work.

This is a standalone Workgroup laptop and not connected to a domain.

I have been trying for days to upgrade this laptop to Windows to version 1903.

The update downloads to 100% and then the laptop reboots to install 1903.

Nothing external is plugged in.

It consistently freezes at 48%.

There is a single C partition so nothing out of the ordinary.

The spinning circle stops.

I have left it alone overnight but nothing changes.

I have used the Windows 10 update troubleshooter.

I have uninstalled all third party apps other than Office 2016.

I have done a disk cleanup to clear out left over files

Currently it is on 1803 so has missed the 1809 upgrade.

I have tried downloading the update through the update option as well as using the media creation tool.

However with a USB stick plugged in I get the not able to upgrade error message because an external drive is plugged in!

I don't want to do a clean install because I don't have the reg key for my Office 2016. (Jellybean can't find the key).

Anyone else with this issue and managed to fix it please?

I fixed the same problem. It was the disk that had errors. I ran CHKDSK /F and the native disk checker of Windows. Then it past the 48% and completed the update

I had the same problem and always got stuck at 48%. I tried multiple times.

The solution - instead of updating using Windows Update, I used the Update Assistant here: -

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

For some reason, this worked perfectly and very quickly without a hitch.

Please try this first, before wasting time with any other "solutions."

Nothing seems to fix this problem. I have tried using windows update and the upgrade assistant. Always 48% before a hang. Reinstalling windows is not an option.
