This will start the GWX App even if it's not running in tray from Run (or IE) Code: ms-gwx:reserve or from cmd: Code: Start ms-gwx:reserve
There is no post in OSBA that talked about it, so I don't really know, from what I read in other forums, seems their 1st MEGA link was pulled down right after WZor posted it in twitter, and OSBA thought that it was WZor's fault.
Nah, 10200 was his first guess, then he knew about the 16 multiple rule, and since there was a difference of 1600 between win7 and win8, so his next guess became 10800.
incorrect, we're already past 10100 and as you can see now, microsoft no longer compiles 30-40 builds /week. it is more likely to be a 10200 build number than a 10800 unless microsoft jumps forward to that number.
