Probably due to MS patched it together, and forget to change the date to agree with the name - per say. that is why I'm using 7106.
Snuffy - use whatever you want. The difference could be because of the digital certification process and the production process of an ISO. The files were probably put together with an 21 date on 17:00 but they didn't manage to put certification on the same day, that's why the 1 day difference. Nothing has been 'patched together'.
when will you just lisin build 7106 is old it come out 3 days after build 7077 making it the same build as 7083 meaning its old
