I got redirected to this forum for Minecraft Windows 10 support but as of yet I have not seen a single thread from Microsoft support members. Are there any here or is this just a community sourced support forum?
Microsoft support will sometimes direct people here -- because Microsoft don't offer technical support for Minecraft directly -- and it can get miscommunicated during that redirection that we are an official venue for support when in fact we are not. From the Minecraft help page:
"UNOFFICIAL HELP RESOURCES
There are lots and lots of other Minecraft players out there so it's quite likely that someone else already have encountered the same problem as you. Therefore the Minecraft community is also a great help resource, especially when it comes to dealing with more technical issues.
Minecraft Forum - Talk with other Minecraft enthusiasts about almost anything Minecraft Wiki - Most likely the biggest Minecraft knowledge base around"
