Analyze possible corrupted files

A very common cause when errors appear when updating Windows, such as error 0x800f0990, is that there is some corrupt file in the system or even several. This can interfere with the execution of different processes, such as Windows update.

What we are going to do in this case is go to Start, look for Command Prompt and run it in administrator mode. We have to run the command sfc / scannow. It will automatically start to check if there is any corrupt file and be able to repair it. This will help us to be able to run Windows updates correctly if it is a problem with a file.

Install updates manually

If we see that windows updates they still don’t work, one more option we have is to download them manually and then install them. This can sometimes be very useful to solve failures that occur in the download and installation, for example.

For this we have to know the update code and then go to the official Microsoft page enabled for downloads. There we have to put that code corresponding to the update and we give it to search, to download the file and execute it.

Try to improve the connection speed

This time the solution is to try to improve our connection. If for example we are connected by Wi-Fi and the coverage is not good, we can always opt for cable when possible and thus achieve greater stability and speed. In addition, we can use Wi-Fi amplifiers, PLC devices or Mesh systems with which to improve coverage and avoid the dreaded dead zones.

Go back to a previous restore point

If all of the above has not had any positive effect, there is also the option to go back to an earlier point in Windows. This feature that is integrated with the system is very useful when failures of this type arise. For example if we have installed a program and it has caused a conflict and has stopped working well, if an update has given errors, etc.

We have to go to Start, we search Restore system and we execute it. Later we give System Restore and it will show us recommended restore points. We can also give it to any other out there. These points are moments in which our equipment worked perfectly and everything will return to that moment, with the corresponding configuration and installed programs.

Restore system to a previous point

In short, if error 0x800f0990 appears when trying to update Windows, these are some of the steps we can take to make it work correctly. We have seen that the causes are varied, although the most normal thing is that it is a corrupt file, a failure with the connection or a problem in the installation process. Generally, it is easily solved when we carry out these actions that we have described.
