If you have already installed the Windows 10 Technology Preview, you may have noticed that the modern version of IE does not appear to be in this version. For the preferred touch-friendly modern version of IE, the following method can open the modern version of IE, but the method also has regrets:
Download PowerShell script directly
Right > "Run with PowerShell" > enter "Y" return
Modern version IE browser will start automatically, then run this PowerShell script can be started (please make sure IE is the default browser)
Unfortunately, the modern version of IE can not be set as the default open browser, each time you have to use this PS script. However, it is important to note that the current version of Windows 10 Technology Preview is still a previous version, some features do not appear in the current release is also normal, Microsoft will continue to improve the next step of the function.
