I've just got some information about Windows 12 development. But, please take it with a grain of salt and understand it could be fake. The fact that I've got information about win12 may be ridiculous but I really got it... First of all, the only (probably) known build is: 11.0.31340.1033 The kernel version has changed from 10.0 to 11.0 This is only an internal testing build, and builds before 30000 can no longer belong to Windows 12. The person who told me these said that the rumour was got when he was talking with someone who gets more about everything inside MS.
