    There's a newer build.

    @Anonymous the Windows Server team on twitter asked me to post it here 2 times now (originally wanted me to post on Technet, possibly unaware that these parts have been moved to Q&A)

    I will try out the new build an report back I would like to point out that b20251 worked fine.

    Sounds like someone was completely out of touch. The product group (Mary Hoffman and company are not active here) which is who you would want to interact with. They are however active in the dedicated Insiders forum I linked.
