@Aravisian As you escaped Windows pre Win10, you missed out on feature updates, which take all night. Then more to fix the resulting mess. So I consider ZorinOS 15.3 to 16 Direct Upgrade would not be a major hardship to Win10 refugees that have landed here.
I do however appreciate that, backup /home, install Z16, re-configure apps and restore /home may take less time for some and end up with a fresh smelling system installation at the end.
EDIT: Consider it wise to monitor Win10 feature update to avoid this: I've finally moved to Zorin OS for good but I have a few questions if someone can help - #35 by StarTreker
