So far I have seen 3 different 7955 builds out there & a 4th one coming soon.
I extracted the .ISO's to look at the dates to try to figure out which is the cleanest.
They all are dated all over the place, probably because the Win7 setup was used on the first leak.
Now someone is claiming theirs has the original Windows 8 setup/installer.
The date on the build is 110228 (2/28/2011)
1st leak = 5/9/11 & 9/23/10
2nd leak = all 9/23/10 dates
3rd leak = 5/9/11 & 3/25/11
4the leak = ?
