I was always very skeptical about the need for search indexing for local files - how often do you search for stuff to need indexing in the first place? I have a ton of files, certainly more than the average Windows user and i do search for things often enough (at least once a day). To search i use Total Commander (allows for both wildcard/regex searches, archive searches, content search with a bunch of options) which doesn't use indexing at all and search speed was never something i had as a problem (and in general i hate waiting for the computer to do stuff).

In what workflows is search needed so often and for so many files that it necessitates indexing? Even back when i first encountered it (in Vista - AFAIK it existed in XP and before but it wasn't enabled by default) i thought it was a waste of resources and unnecessary complexity.
