With Windows 8 build 7955 leak, comes another new feature that Microsoft is secretly working on -- the "immersive browser" is a unique Metro UI-style browser.
"The browser offers users a very limited UI and navigation bar. With only a couple of options including the back and forward history buttons, an address bar with favicon, a refresh button and favorites, the browser offers a compact browser without all the unnecessary bloat."
Another feature that's revealed is the "History Vault" -- basically a backup and restore feature, similar to Time Machine for Mac OS X.
"History Vault will manage all your saved files through a timeline (found on the bottom), so users can restore edited or deleted items."
