This is how you can avoid error 0×80070643 when updating Windows

Keeping your operating system up to date is essential for any user, both personal and business. Security updates fix system vulnerabilities and improve system performance.

Many people don't dream of updating their operating system properly. Postponing updates can leave your computer exposed.

Windows is the most widely used operating system in the world, but it is also the most vulnerable. That is why you must always keep it updated to avoid any problem.

Recently, some users have reported that when updating Windows, it gives them an error code 0x80070643. If it has happened to you, don't worry, today we will tell you how you can solve it.

What is error 0x80070643?

It is important to mention that this is not exactly a current error. That is, this is a fairly common error that can occur in any version of Windows, not just 11.

In fact, there are many reasons why this error can occur, the most common being a driver problem. Sometimes it can happen when installing a program that could not be installed correctly. This can happen when an update has not been completed.

This creates corrupt files and at the time of an update, Windows detects them and throws this error. Of course, this is not the only reason as it can be due to some malware on your computer and others.

How to solve this problem?

Now that you know what the causes may be, the next thing you need to know is how to correct it. Depending on what happened, you can resort to one solution or another. Next, we are going to talk about them.

Scan your computer for viruses

We said that viruses can be one of the causes of this error. That is why one of the easiest solutions is to scan your computer for malware.

Ideally, you should have a good antivirus on your computer that can stop them, but it is not always possible. That is why you can scan your computer to find the culprit.

Windows Defender is available in the latest versions of Windows, which is the system's built-in antivirus. Today, this has become a very good security option.

You can use it and it will help you find and remove any type of virus that may be on your computer. After finishing the scan and virus removal, you can try the update again, which should work.

In the event that this error continues to appear, you can choose another of the options that we will tell you.

Search for corrupt files

Another thing you should do is search your computer for any type of corrupt file that may exist. This is one of the most common causes for which this error can appear, so it must be ruled out. Fortunately, Windows can help you and you won't have to search for them manually.

To start the search, you will need to open a terminal, so in the Windows 10 or 11 search engine, search for “cmd” and access the first option. Another way to do it is with the shortcut "Windows + R" and in the window that opens write cmd and press enter.

Once inside the terminal, run the command sfc /scannow and it will start scanning your computer. In the event of any corrupted files, this will detect and repair them. Reboot your computer and run the command again to verify that everything is ok. If there are no corrupted files, you will be able to download the updates normally.

If the error still persists, don't worry, we still have several alternatives to solve it.

Restart Windows Installer

Another reason why the error 0x80070643 may appear is because there is something wrong with the Windows Installer. This program can “get stuck”, causing updates to fail to install.

To solve it, you will have to access the search engine again, but this time you will have to write "services" and once inside you will see all the active services. You will have to search for “Windows Installer” and when you find it, you will have to right click and then restart.

When you do this, try installing the updates again and you should have no problems.

Check that there is no program interfering

This is not as common as the previous cases, however, it may happen that some program is interfering with the update. In the event that you have a proxy program, VPN or even an antivirus, it is recommended to disable them all and try downloading them.

When this happens, one of these three may be to blame, but really, any program can interfere. If you have installed any programs since the last update, you can remove them and try again.

Update the.NET Framework

This is a vital component for the proper functioning of many programs in Windows. When this component is not installed in the operating system or is simply not up to date, it can cause problems with updates.

If this is the case, the solution is quite simple and just downloading the latest version will be enough to eliminate the problem. To do this, go to the Microsoft website and download it directly from there, this way you make sure that there is no problem.

These were the most common ways to resolve error 0x80070643 in Windows. So, with some of these options you will be able to solve the root problem. We recommend that you apply the solutions in the order that we mention them, since they go from the most common cause to the least common.
