More information regarding Windows Blue has leaked onto the web today, revealing IE11 and a public preview of the OS.
It was originally thought that Windows Blue would hit M2 before being released to the public, however another source claims Windows Blue will hit an MP build which will be released to the public for testing before M2 and RTM. MP stands for Milestione Preview.
Also, it appears Windows Blue is packing a newer version of IE, IE11 to be exact. Not much else has been said on this, but the image below does seem to confirm it.
Remember, the information above could be false. Read with caution.
