Disable Windows Search
If you want to deactivate Windows Search, you have to switch off the standard search in the service management. That's how it works.
Windows Search - Call service management
- Click [Start] (older Win versions) or [Windows key + Q] for Windows 8.
- Enter "Services" in the input field.
- Press the [Enter] key.
Windows Search - administer service
- In the "Services (Local)" window, look for the entry "Windows Search".
- Double-click the entry. Under "Service Status" click the [Exit] button. If you want to prevent "Windows Search" from being activated again in the future, carry out step 3. If you do not want to make any further changes, press the [OK] button now.
- Under "Startup Type", click the dropdown box and select the "Disabled" option. Then click the [OK] button.
