First, we need to go to Local Disk (C:) -> Windows -> SoftwareDistribution -> .
Inside, there will be a crapload of folders with weird names.
We need to select them all (with Ctrl+A) and delete them. Delete everything.
We will need to provide permission...
...and wait a couple of minutes, because those folders contain tens of thousands of files.
After we have deleted everything, we need to open a command prompt with rights. Just search for CMD, right-click and "Run as ".
There, we type:
wuauclt.exe /updatenow
After that, we reopen Windows Update, and we should be good to go.

If the above solution didn't work for you, try to change the date of your PC to a couple of days later, this has helped several s.
If that still doesn't work, create a Windows 10 USB, so you can even upgrade Windows offline.
