Please be careful when using Windows 10, because any security vulnerabilities envolving Windows itself will not be fixed, and your computer will be more vulnerable to attacks. I’m not saying this to scare you off, but to advise you to take extra precaution and to remind you that most computer security experts do not recommend using and connecting to the Internet systems that will get no further security updates. I’m no expert myself, but I’m pretty sure that things like making sure you web browser is always updated, being careful with the programs you choose to download, and using updated antivirus software are the most common tips for this kind of situation. You might want to do more your research on this topic yourself if you haven’t yet. Stay safe!
