Microsoft is constantly releasing updates after updates to make the users’ experience better while operating their system. Lately, however, the Windows 10 Update KB5003637 has come across some issues as it is either stuck at 0%, 99%, or even 100% or it just fails to install with errors such as 0x80070002, 0x80070003, or 0xc19004303.
Today however we’ll get through this issue together and make sure your update is installed for good. So, let’s start with the first step to resolving this:

Reasons as to Why It’s Failing

The main reasons as to why the Windows update could be stuck or failing are the following:

Easy Fixes

Regardless of what the reason is, the result is always the same. In order to get through the majority of these issues all that you’ll need to do is you’ll need to follow these quick instructions and you’ll have your update installed in no time:

  • Always make sure that you have a stable internet connection
  • Check to see if your time and date settings are up to date
  • Take a look at your System Drive to make sure that you have enough free disk space for the update
  • Make sure to disable third-party Antivirus and the firewall on your PC
  • Commence the Windows 10 Clean Boot and always check to see if there are any updates out there

Run the Windows Update troubleshooter

If none of those methods managed to get your update rolling then you need to run the built-in Windows Update troubleshooter for good measure. Here is how you do that:

  • Press Windows + I, in order to get to Windows Settings
  • Click the Update & Security option, then click on Troubleshoot
  • Click on Windows Update, then click on the Run Troubleshooter option

After this is done check to see if the troubleshooter has identified any issue whatsoever. If it did, make sure that it’s fixed right up and then update your computer for good measure. This should fix your problem.

Update the Installation Files

If the problem still persists, however, it’s time that we took a look at the Windows Update components to make sure they’re not the problem. So, delete the previously updated installation files from the software distribution folder. Here is how you do that:

  • Press on Windows + I and from there open up the File Explorer
  • Stop the Windows Update service . Open Command prompt as administrator and type this command (without qoutes) and press Enter key.
    • Command : “net stop wuauserv”
  • Go to C:\Windows\SoftwareDistribution\Downloads
  • Click on CTRL + A and select all the files in the Download folder and delete them

Sometimes you may not be able to delete those files because of any usage lock. Then you have to restart the system and redo the steps mentioned above.

Restart the Windows Services

Next up we will be restarting the services that you essentially took out beforehand. Here’s how you do that:

Open Command prompt as administrator and type this command (without quotes) and press Enter key. 

net start wuauserv

Alternatively, you can start the Windows Update service through services.msc console.

  • Open up the Windows Services [Click Start menu -> type services.msc -> select Services App]
  • Double Click on the service named “Windows Update” -> Select Start from the startup type dropdown list -> Press OK to start the service.
  • Restart your computer and check for updates

Run a System File Checker (SFC) Utility

SFC tool will scan the integrity of all system files and replaces them if any corruption founds.

If even that doesn’t seem to work out then you can always just run a System file checker Utility on Windows 10. Here’s how you do that:

sfc /scannow

The file checker should now proceed with scanning your whole computer for issues. If there are any out there then the file checker is sure to find them.

Run DISM – Deployment Image Servicing and Management tool

DISM tool will scans the system image for any component store corruption, and repairs it if required.

dism /Online /Cleanup-Image /RestoreHealth

After these processors, you can once again just restart your computer and wait for the changes to be set up.

Manually Install the Update

But sometimes the file checker isn’t enough to find the issue at hand. That’s why you need to manually install Windows Updates in this case. In order to do this, you need to get to the Windows 10 update history webpage right here: https://support.microsoft.com/en-us/topic/windows-10-update-history-0d8c2da6-3dba-66e4-2ef2-059192bf7869
Check for the latest update and note down the KB number. Next up just use the Windows Update Catalog website to search for the update and download it. Make sure you download the right update for your computer (x86 or x64).

Switch to Google DNS

You can also switch to Google DNS to try and fix the problem. Here’s how you do that:

  • Press on the Windows key + R, type ncpa.cpl and click ok
  • Right-click on your active network adapter and select properties
  • Change the DNS server 8.8.8.8 and Alternate DNS serve 8.8.4.4
  • Validate your new settings and click ok apply
  • Open up your Windows Update and Check for Updates

Final Steps

If even that isn’t enough however you can always follow these steps as well:

  • Disconnect from VPN or any other security software
  • Remove all of the external storage media (USB drives, SD cards, etc.)


That should in turn get your issues with installing the free Windows Update solved. Make sure that you go through every step accordingly. If you want to get the problem solved since most of the time it is something very small and tedious that caused the error, something that can be cleared up by simply restarting your computer or checking your internet connection.
