Not sure I agree with "spacewaste" it should make no difference to his music folder load time as far as I can see because he is not doing a search the system knows where the files are from the filenames in the directory, ie the files are already indexed.
I hardly ever do any searching so I think switching it off will improve things so I am switching it off. 99% of the time you will be indexing garbage.
I can always switch it back on again if it seems worse.
All microsoft applications are shyte IMO so the less running the better!!
