Hello. I tried updating Windows, but every time I receive an error with a code 0x80240016. I have tried restarting my PC and trying again, but that did not work. Do you know what could fix this problem?

Solved Answer

Although Windows is one of the most popular operating systems around the world, it does not come without any issues. Windows needs to be constantly updated, to receive the necessary security patches^[1] and other fixes. If that fails, users might experience performance issues like lags and crashes. Sometimes the cause of system issues is the updates themselves.

Some of them can corrupt system files, that later need to be fixed manually. Microsoft has created built-in automatic troubleshooters that that can fix many errors themselves, but that is not the case with the 0x80240016 update error.
