Microsoft have unfortunately found multiple ways to "influence" us into upgrading to Windows 10 so be very careful regarding what you click and make sure your read all the information.
At the bottom of this post you will see 4 screenshots which demonstrate one way they have "guided" customers to upgrading. You need to physically tell them that you DON'T want to upgrade instead of the other way around. We have shown you below how to avoid the upgrade.
We hope this information information will save your potential future frustrations and costs.
