Solved Answer

Although Windows 10 is considered to be a well-engineered piece of operating system that features a handful of useful and innovative services, there are lots of unfinished tasks or Windows 10 gaps, which lead to system errors and BSOD windows. This time, we would like to explain what is Error Code 80240020, why does it happen, and, of course, how to fix it.
80240020 Error happens when a user is trying to launch Windows 10 update. This issue reached its peak of occurrence at the beginning of Windows 10 upgrade. However, quite a lot of Windows users report about it these days as well. The reason of 80240020 error a year ago was related to the overloaded Windows servers, which caused the download of incomplete or corrupt system files. Concerning this error in relation to Windows 10 Anniversary Update, the cause remains the same – incomplete/corrupt files. However, this barely happens due to overloaded Windows servers.

Once 80240020 error code shows up, you will be asked to restart the PC/laptop, so that the update could resolve. Unfortunately, but restart will not fix the issue because when the system will boot up and you will try to launch the update again, you will see nothing except this error again. Therefore, you have to perform some troubleshooting steps to fix 80240020 error permanently.
