Basically a woman who runs her own biz had/has a computer that started to download & install 10, the update failed, & it probably tried to roll back to the previous copy of Windows, since that's standard procedure. Rolling back like that doesn't always work -- been there -- and in her case messed up her computer so it was not usable, costing her time & money. She sued, won, MS appealed, but ultimately decided it wasn't worth the relatively small sum [to MS] of $10k, so dropped the appeal.
