I don’t remember installing Windows Desktop Search (WDS) on my notebook but one day it was there. I think they maybe slipped it into the installer for a trial app or something I tried and then dumped for being crap. The trial app went away but for some reason WDS stayed.
The two things I noticed after it appeared were the new Search Desktop input field hogging much of the Taskbar and the new searchindexer.exe process hogging most of the CPU. The mostly nonstop churning of disk activity also suggested something was amiss.
Troubleshoot, isolate, try different settings, pray: I tried all of the standard steps one tries when trying to get buggy MS software to work properly, but all to no avail. Finally I disabled the service and will remove the thing altogether in a few minutes. Thanks, Bill, for another couple hours of wasted time.
To summarize, if you’re looking around the net for info and reviews of WDS and found this, take my advice: don’t bother with it. There are better desktop search options out there, use one of them instead.
