Use Edge Instead of Internet Explorer
If you are a Windows 10 user and browsing the web, you should stop using Internet Explorer. At least if you're not forced to for work reasons. It is outdated and insecure at this point, but luckily there is a much better alternative by Microsoft. Their "Edge" browser can import your settings/bookmarks from IE and provide more security. It is also much faster than Internet Explorer and behaves much like Google's Chrome browser. You can read PDFs in Edge built-in, instead of using Adobe Reader.
