Don?t Use Expired Windows 8 Developer Preview Build 8102 M3 - After March 8, 2012 - SoftpediaEarly adopters currently testing the first public development milestone of Windows 8 lose all rights to use the Developer Preview release once Build 8102 Milestone 3 (M3) has passed its expiration deadline, according to Microsoft.
As is the case with all pre-release software, and Windows 8 Build 8102 M3 is as pre-release as it gets, Windows Developer Preview is time-bombed.
This means that Microsoft has slapped an expiration date onto the first public test Build of Windows 8.
