How to Reinstall All Windows 8 Modern Apps on a New PC. I don't know when Metro became Modern. But, the apps you install from the Windows 8 store that sit on the main Windows 8 screen, and which are optimized for Windows 8 are now called Modern Apps. I will continue to call them "the apps formerly known as Metro". But, I digress. What if you get a new Windows PC? Or you wipe the old one? Much like Google Play Store, the new Windows 8 Store gives you a one click option to reinstall all your Metro (Modern) apps. Easy.
