Think what you want about 4chan, but I generally start with the links in the OP of the "/g/ - Technology" board's regularly recurring "friendly windows thread". Being 4chan, it is decidedly unfriendly, but the guides in the OP are usually good. Always read up thoroughly, fully, and apply your own common sense before using any tools or running commands.
Wish I could be more specific, but I'm still using 10, so I'm not familiar with the 11 specific stuff.
