As mentioned yesterday, Microsoft released the new Windows 10 preview build 11099, which is the second version of Redstone and the first of the new year.
The company doesn't seem to have made any major changes to this build, and Gabriel Aul, head of proletterWindows Insider, said the same will happen for future releases, as developers improve performance and fix whatever errorthey are possible.
As with all the previous builds available from Microsoft on Windows Insider's Fast Ring, this has also been released from unofficial sources.
