Windows 10 May 2019 or version 1903 Update stuck at downloading

Microsoft has already started and almost completed the Windows 10 version 1903 rollout. Except for a few users, we assume practically every Windows 10 user has already updated to the new version. Even if you have not, it is advisable to update your system to ensure that you do not end up with no support version. For instance, you are on Windows 10 version 1803, you will not be supported anymore, and it is advisable to opt for the latest version right away. Microsoft takes it up with forced updates to ensure that users do update to the latest version if they are on any of the unsupported versions.

Several users have been reporting that the Windows 10 version 1903 update gets stuck at a certain percentage while downloading the update. Ideally, there are many cases where you will find the update getting stuck at 99%.

Several fixes can help you address the issue, and we will check them out one by one.

Method 1 – Run Windows Update trouble-shooter

Microsoft has already released the Windows Update Troubleshooter and using it should resolve the issue in many cases. This can help you address the problem and fix the Windows 10 update issues.

Here is how you would be able to do it –

Launch Windows 10 Settings.
Choose Update and Security group
On the right-hand side menu, choose the option Troubleshoot
On the left side, locate the heading for Get up and Running and click on Windows Update section for an effective troubleshooting option.

You should get the option to run the troubleshooter. Click on it, and the update procedure should begin.

The troubleshooter will attempt to resolve the issues affecting your computer and fix the problems automatically in most cases. After the troubleshooting process is completed, you can restart your computer and check for the updates once again. Most of the update issues are resolved using the Windows Troubleshooter option.

Method 2 – Reset Windows Update Components

One of the culprits that can cause the issue with the Windows 10 version 1903 update getting stuck on 99%b or any other value. Resetting the Windows Update Components should ideally resolve most of the update and installation issues.

Follow the steps here below –

Launch RUN dialog box. This can be done by pressing the Windows key and R simultaneously.
Type in the command MSC and click OK
Locate the following services and stop them

Windows update
BITs
Superfetch

Launch the File Explorer on your computer
Locate the folder C:WindowsSoftwareDistribution
Delete the folder. If you do not want to delete the folder, you can rename it to bak
Launch the MSC once again and start all the service that you have stopped.

Close all the windows and head on to your Windows 10 Update option and check if the update is available and works.

Method 3 – Run DISM and SFC utility

The corrupted system files can be one of the huge issues that can cause the problem for your Windows update. In many cases, SFC alone can resolve the problems in your case. However, there are some situations where you may find that the SFC utility fails to work. In such cases, it may be practical to run the DISM tool before running SFC.

Here is how you would complete the troubleshooting method –

Launch Command Prompt on your Windows 10 device.
Run the Deployment Image Servicing and Management or DISM tool using the command below

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

The tool will run and fix any of the components that may be affecting your system.
Once that done, run the System File Checker using the following command

Sfc/scannow

Wait till the scan is completed. This will take a while depending upon the number of files available on your system.

Method 4 – Update the missing drivers

The drivers can be yet another culprit that can address the issue in your case. Reinstalling the drivers can be one of the best options that would be helpful for you.

Perform the following steps to update the drivers –

Launch Device Manager on your computer. You can do so in several ways. Search for it using the Windows Search option and choose it from the search results. You can even use RUN dialog box and type the command msc
Expand the categories for the devices and check if there are any yellow marks against any of the devices.
Update the driver for the device. This can be done by right-clicking on the device and click on Update Driver from the context menu.
Follow the onscreen instructions and complete the driver update.

You can even consider downloading the latest driver from the manufacturer website. Make sure you are downloading the driver specifically designed for the particular device model you are installing it for.

Method 5 – Use a WIM image to resolve the issues

This is one of the best options that can help assist you in resolving the issue and handling the Windows 10 Update to Windows 10 version 1903 without getting stuck in the middle.

Ideally speaking, the DISM should resolve most of the problem without any issues. However, if you are still facing issues, it may be a good idea to opt for a third-party source. You can follow the steps here below to address the concern –

Visit the Microsoft support site at this link.
Click on the Download Now option
Double click on the MediaCreationToool.exe link.
Click on Accept and agree to the terms and conditions.
Choose the option Create installation media (USB flash drive, DVD, or ISO file) for another PC
Click on Next
Enter the details like language, edition, and architecture (whether 32 bit or 64 bit) and click on Next
Choose the ISO file option
Follow the instructions to save your ISO file.

Once the ISO image is downloaded, double click on it to mount the image. Check your ‘File Explorer.’ Once that done, use DISM to resolve the update issues.

Here are the steps you would need to follow –

Launch Command Prompt
Type in the following command

DISM /Online /Cleanup-Image /RestoreHealth / Source:F:sourcesinstall.wim

The source here is indicated as F:sourcesinstall.wim is only for instruction purpose. Replace it with the exact location of your source file that you have mounted your ISO file on.

That should now do it, and your issues should be resolved without any hiccups.

Check if leaving the update to complete on its own may take thee update forward and help you download the update without any problems. It may be worthwhile to notice that a faster and reliable internet connection can be a great choice.

A minimum disk space is yet another option that should need to check out. A minimum of 32 GB disk space would be a must to ensure the trouble-free update. In some cases, the third-party antivirus may have been restricting the update from downloading and installing. Check if you can disable the anti-virus service. In fact, it cannot be disabled. You can even uninstall it and can opt to install it once again after you have installed the Windows update successfully.

Another issue that can cause the problem on your Windows 10 device will be to check if the regional settings are correctly configured.
