I have a 520, and windows 10 works okay. not as fast as windows 8, crashes sometimes. but it feels good on some places. But it only took me like 2 hours to download and install. so I don't see how good it's it's taking days to install.
I guess it would be better to have made sure you had all your important files on sd card, and hard reset that phone.
Update takes a while, but not days for sure.
