Someone will figure out how to turn it off again in fairly short order (it might be as simple as a mklink to NUL for the storage directory, causing it to send its recordings into the void). What irritates me more is the typical Microsoft misuse of the word "feature".
(I mean, this thing does have some potential uses (imagine being able to see what that elderly relative you provide tech support for actually did when they claim they "did nothing"), but the privacy concerns vastly outweigh them.)
