Cannot update Windows 7

I have a x86 Windows 7 VM (using VirtualBox), and I am trying to update windows. The problem is I can't. Every time I try to update it I get the following error: 8007000E

So, to fix it, I added more memory to it, now it was 3GB of RAM. But that didn't fix it. I also found this solution on a windows forum which advised me to run the troubleshooting app.

After doing that, I end up with another error, albeit a different one: 0x8024402C.

After investigation I ended up in another windows forum discussion thread which led me into updating the Windows Update Agent (the updater needs an update ... ironic :D ).

But nothing works, and I am starting to get desperate. What am I missing? Why I can update my windows?

I think Virtual Box is not compatible with the upgrade (as I've not used it, but I know quite a bit from it). Check your internet speed as well. Also, look for the minimum requirements for Windows 10 and set the VM settings to those requirements. If you want more flexibility you can switch to VMware for that. If you do a bit of googling and be a liitle smart, you can get the hard disk image running in VMware without reinstalling Windows 7 all over again.
