When Windows 10 came out, I purchased a computer with that on it and tested Internet Password Lock on it, so the short answer is yes. However, I will admit that there are various configurations of Windows 10, various types of virus protection that people have, and of course the ongoing upgrades provided by Microsoft, so I cannot guarantee that it will work with every computer running Windows 10, or that it will continue to work if Microsoft uploads an upgrade that suddenly makes it incompatible. I recommend installing it and trying it for at least a few weeks of the 30 day trial period, and deciding for yourself if it is worth the investment. As for the person who said it hung during installation, I cannot explain that, but I can say that I have had all sorts of programs hang during installation, so that does not prove that Internet Password Lock does not work on Windows 10.
