It is also the safest way to install versions as old as Explorer 6 or 8 since it allows us to isolate the use of these browsers from our system. These machines allow us to run another operating system as if it were an application inside our PC. In a native way, it is not possible to run versions lower than Internet Explorer 11 on Windows, so it will be necessary to install a virtual machine. The main problem that we are going to have to install old versions of IE on a recent computer is compatibility.
