Hello everybody!
In today’s video, I’ll show you what do if you tried updating your Windows operating
system and encountered this error 0x80070490, and how you can
fix it.
This error often appears when people try to get the latest version of Windows using the
Windows Update service.
Why you see it One of the main causes of this error 0x80070490
are damaged components of the Component-Based Servicing package manager.
As a result of the damage, the installer cannot complete the update, so the system cannot
be updated without the user taking some extra steps.
In addition to Windows 10, the previous versions - Windows 8 and 7 - are also vulnerable to
this problem.
How to fix it There are several ways to solve the problem
with downloading and installing updates with Windows Update.
With the System File Checker tool With the System File Checker tool, which is
a built-in utility for recovering damaged system files.
To start it, you need to use the Command Prompt.
To do it, type “cmd” in the search field and click to start it as Administrator.
In the Command Prompt window, type the following command:
sfc/scannow It starts scanning the computer, which should
not be too long.
When the scan is over, close the command prompt window and restart the operating system.
As soon as you’ve done that, Windows Update should work properly, and this error should
disappear.
Restart the Windows Update service If the first method didn’t help you, try
restarting the Windows Update service.
In the search field, type “Services”, then find Windows Update and open it.
In the window that opens, make sure the startup type is set to “Automatic”, stop it, and
then start it again.
Otherwise, right-click on the service and select “Restart.”
After that, check if you encounter the same error again.
Restoring Windows Update components The second method is restoring Windows Update
components.
For that purpose, you have to stop the BITS and Windows Update services first.
Then launch the Command prompt as Administrator and type the following command one by one:
After that, rename backup folders of distributed software by using the following commands:
After that, reregister all files of the BITS service and Windows Update with the following
commands.
… After reregistration, start the services that
have been suspended before.
You can find the list of all commands in the description under the video.
To save the trouble of typing all of them one by one in the Command Prompt, it’s better
to create a .bat file with these commands.
You can watch one of our videos to see how to create such a file, and the link is below,
under the video.
System Restore If the error is still there, the next thing
you can try is to restore your system.
However, it is only possible if you have configured system protection options and created a restore
point for your system drive.
Type “rstrui” in the search field to use this function, then click Next, choose the
latest restore point, then “Next” and “Finish.”
You will see a warning that system recovery can be stopped only after this process is
over.
Choose “Yes” to start the restoring process.
The computer will restart and begin the operation at once.
Wait until the process is over.
Deployment Image Servicing and Management If you still see this error on your screen,
use the Deployment Image Servicing and Management tool.
This tool works from the Command Prompt, so start it as Administrator and type the following
command: DISM.exe /Online /Cleanup-image /Restorehealth
This process takes some time so wait until it is over.
For correct work, the computer should be connected to the Internet.
The Troubleshooting function To eliminate this problem, you can also use
the standard troubleshooter utility.
Go to Settings / Update and Security / Troubleshoot.
Find Windows Update and click on “Run the troubleshooter.”
The system will start searching for problems, if there are any, you can fix them by clicking
here.
With a third-party utility, Windows Repair If integrated utilities fail, here’s one
free tool for correcting Windows errors.
The only disadvantage is that it doesn’t have any multilingual support, so English
only.
However, anyone regularly dealing with restoring computers back to normal will understand the
menu items (and such people are actually the target audience of this tool).
You can download it from the official website by following the link below this video.
Start the program and accept the license agreement.
Go to the tab “Repairs” and choose “Open Repairs.”
You will see a warning saying that you haven’t started the program in safe mode, and that
in this case third-party programs like your antivirus may get in the way when you try
to correct errors.
You can safely close this warning.
Here, choose “Windows Updates” and click “Start Repairs.”
After that, the process of correcting errors will begin; when it is over, you will be suggested
to restart the system for the changes to take effect.
Also, this problem can be caused by a virus.
Check your computer for malware.

Finally, if all the tricks still don’t work, the only thing left to do is to reinstall
or reset the operating system.

That is all for now.
