Recently I have a problem with the Search feature. The "Settings" app items like Check for Updates are not included in Search or search box in Settings app anymore, only items from Control Panel are shown. Seems like this problem happened after last update Windows automatically installed (KB3074683). Is there any known fix for this problem? Restarting Windows Search service and resetting the search index won't help. My system is upgraded from Windows 8.1 Pro to Windows 10 Pro.

Here are some screenshot showing the problem:

The "update" keyword should return some Windows Update from Settings app items alongside with Control Panel items above, but now they just return the Control Panel items.

Same thing happened when I search from Start Menu.
