I just reduced the things it indexes and got 25% of my CPU back (has been higher), in fact it now indexes nothing. XP worked fine without it in fact it was faster despite have 1/4 the CPU speed. As a computer programer I am pretty sure for 99% of user this will only make things. It is like indexing everything in your home so you can find it faster, you shift so much stuff around you can't find anything. Pile of crap. It like defragging, makes no difference and wears the bearings of your hard drive into dust.

Microsoft's attempt to collect data on users by indexing their entire hard drive. Inefficient, unnecessary, and a privacy nightmare. Better to disable Windows Search and install a 3rd-party app, unless you are lucky enough to be using XP or older.
pc becomes very slowly and RAm is full when active. Just kill it and good...
it is simply windows search service. Do not bother about it

This is a Windows program which improves Windows Search Engine. Used deribelately it could be really useful and unexpectedly helpful. The only thing you need is to configure it.

Come on people! Its part of Windows. Its a pain in the but but you shouldnt take it out. You can modify it to only index a few needed things. Look it up in the net.

It's purpose is to help you to find your files fast. But it continously reads disks and consumes memory and cpu. Just a useless MS tool, should be disabled..
I know that it totally killed my HP mini. The update also turned all the services that i disabled previously back to automatic. took over 10min just to get to the run prompt. be patient.
