Fix: Start Menu Cortana Search Not Finding Apps – Search Results Blank

When you use Cortana search to find an installed program, the program may not appear in Start menu search results although the shortcut exists in the Start menu folder. For example, with Word 2016 installed and its shortcut present in the Start menu folder, when you type in “word”, the search results will display WordPad and other default results except Word 2016. This is not specific to the Office suite but also happens for other programs.

Fix: Start Menu Cortana Search Not Finding Apps

The Indexing Options may show “Start Menu” in the list of included locations. Also, rebuilding the index does not help. This bug seems to have appeared first in Windows Creators Update (v1703), and remains unresolved in the Fall Creators Update (v1709).

Fix 1: Allowing Background Apps Resolves the Issue

Redditor /u/Drimzi has found that the Start menu search will not update if background apps are disabled to conserve battery power. To fix the search problem, enable the option “Let apps run in the background” in Settings > Privacy > Background Apps. It doesn’t matter if you disable every app in the list, but enable the master switch “Let apps run in the background“.

Start menu search can not find installed programs from Windows10

The above setting can be configured using the Registry Editor as well. Start regedit.exe, and navigate to the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\BackgroundAccessApplications

Right click BackgroundAccessApplications, and select New > DWORD (32-bit) Value.
Name the value GlobalUserDisabled and set its data to 0.
Exit the Registry Editor and restart Windows.


Fix 2: Reinstall Start Menu and Cortana Using PowerShell

Open Task Manager → Details tab, and terminate StartMenuExperiencehost.exe process if it’s running.

Launch PowerShell as Administrator, and run these three commands one by one and press ENTER:

Get-AppxPackage Microsoft.Windows.StartMenuExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Note: If StartMenuExperienceHost.exe is running when the above command is run, you’ll get the following error:

Add-AppxPackage : Deployment failed with HRESULT: 0x80073D02, The package could not be installed because resources it modifies are currently in use. error 0x80073D02: Unable to install because the following apps need to be closed Microsoft.Windows.StartMenuExperienceHost.
Get-AppxPackage Microsoft.Windows.ShellExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Get-AppxPackage Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

This reinstalls the Start menu (StartMenuExperienceHost, ShellExperienceHost) and Cortana. Restart Windows and see if Cortana is able to find Start menu app shortcuts. See also Reinstall or Repair stuck Windows 10 Start Menu & Taskbar, and Fix “Critical Error”.

Note: If you have problems with Windows Search (not just with Cortana) not finding files correctly, follow the instructions in article Reset and Rebuild Windows Search to Fix Indexing Problems.


Windows 10 Start Search Results Empty & White Screen appears

Here is a similar Cortana issue.

When you type something in the Windows 10 Start search (Cortana), the results page may be completely empty, showing only the white background. Also, the options namely All, Apps, Documents, Email, Web, and More options are missing at the top.



Windows 10 Start (Cortana) Search Results Empty & White Screen

Let’s see how to fix the Windows 10 Start Search (Cortana) white screen issue in this section. This issue is different than the “Search not finding apps” problem. The blank white screen doesn’t sound like a Search indexing problem. Rather, it could be a malfunctioning Cortana app or a corrupted Cortana data store.

Generally, when Cortana has no local or web results that match your keyword, it offers you the See web results option under Best match. Whereas in the above case, the entire Cortana screen is empty, just showing the white background. This suggests the Cortana app or its data store got corrupted.

Windows 10 Start (Cortana) Search Results Empty & White Screen

Resetting the Cortana data store or reinstalling Cortana should fix the problem. Follow the steps below.

Fix 1: Reset Cortana via App Settings

  1. Click Start
  2. Right-click Cortana → More → App settings
    Windows 10 Start (Cortana) Search Results Blank & White ScreenThis opens the Cortana app settings page directly.
  3. Click Reset
    Windows 10 Start (Cortana) Search Results Empty & White Screen
  4. Click Reset again when you see the message “This will permanently delete the app’s data on this device, including your preferences and sign-in details.”

Fix 2: Reinstall Start Menu and Cortana Using PowerShell

If resetting the Cortana app doesn’t help, try reinstalling the ShellExperienceHost and Cortana using PowerShell.

  • Launch PowerShell.exe as Administrator, and run these two commands one by one and press ENTER:
    Get-AppxPackage Microsoft.Windows.ShellExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
    Get-AppxPackage Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

This reinstalls the Start menu (ShellExperienceHost) and Cortana. Restart Windows and see if Cortana search results page is fixed.


Fix 3: Rename the Cortana data folder manually

To rename the Cortana data folder of your user profile, you’ll need a second administrator account. This is because when you’re logged in, the Cortana data folder of your profile is in use by searchui.exe, Cryptographic Services, dllhost.exe, and other Windows processes.

  1. Open Settings → Accounts → Family & Other users → Add someone else to this PC.
  2. Create a 2nd administrator account (say, TestUser) on your system
  3. Logoff the current user account (say, User1)
  4. Log in to the newly created administrator account.
  5. Open File Explorer and browse the following folder (of User1):
    C:\Users\{User1}\AppData\Local\Packages\
  6. Rename Microsoft.Windows.Cortana_cw5n1h2txyewy to Microsoft.Windows.Cortana_cw5n1h2txyewy - OLDstart search not launching programs - white screen
  7. Logoff the new user account
  8. Log in to your original account (User1)
  9. Reinstall Cortana again as mentioned in Fix 2.
  10. Delete the newly created (TestUser) user account.

Many users have indicated that renaming the Cortana data folder from a 2nd account has resolved the empty & white Cortana search results issue.

[Solved] Programs can’t be launched from Start Search results

Resetting the Cortana data folder as in Fix #3 above also fixes a problem where when you search for a program via the Start menu, programs don’t start when launched from Cortana Search results. Refer to the Reddit thread Windows 10 Search Bar won’t open programs that are not listed as “Trusted Windows Store App where many users have indicated that renaming Microsoft.Windows.Cortana_cw5n1h2txyewy has fixed the problem of Start menu search results not launching apps when clicked on them.
