|It is indeed Windows Search that causes this. And unfortunately if you use Outlook, you need it to search through old emails.|
But it is possible to get the old trusted Search Companion back with the following steps:
First you have to have started the Search Companion at least once: Click on Search and then select the Search Companion at the bottom. This will create a registry key that we now can change:
Simply open RegEdit (hit Start > Run then type 'regedit'). Go to the following node:
HKEY_CURRENT_USER\Software\Microsoft\Windows Desktop Search\DS
Then double-click on 'ShowStartSearchBand' and set the value to '0'. Close that and you're done, the next time you click 'Search' in explorer, the old, reliable search companion will appear.
If you are not really using the new Search, you can disable most of the indexing. Right-click on the Loop icon in the task bar and select "Windows Search Options...". Click on Modify, then click on each selected location and de-select. From this icon you can also still access Windows Search.
