W10 upgrade failed (error 80240020) - I didn't ask it to

Hi,

I got the little 'Get Windows 10' icon and reserved my copy, all fine. But it still doesn't actually say it can install, not sure why. But my laptop has now tried to install W10 5 times, without telling me it was going to or asking my permission. And all five times it has failed with error code 80240020. This is not my area of expertise and I don't know why it keeps doing this. I'm not even sure I want to install it; I only reserved it to see what everyone else thought and I figured I'd have some kind of say in the matter.

Basically, is it supposed to do this? And what can I do to fix it, either by stopping it trying or installing it properly?

Thank you :)

Don't worry, it's not your mistake(at least it's not that you have done smt wrong), this failure belong to microsoft server or your internet connection. You can find the reasons and solution here
