Enable or Disable Copilot File Search on Windows 11

First, ensure you have the latest Copilot app with file search capabilities. Open the Microsoft Store and check for updates.

Get-AppxPackage -Name "*Copilot*" | Select-Object Name, Version

Navigate to Microsoft Store > Library > Get updates. Look for Copilot app version 1.25034.133.0 or newer. If not installed, search "Copilot" in the Store and install it.

Open the Copilot app and navigate to the settings where file permissions are managed. This is where you'll control file search and read access.

Launch Copilot app, then click the maximize button or drag to expand to full view. Click the Account button (profile icon) in the top-right corner, then select Settings from the dropdown menu.

Control whether Copilot can retrieve and index your local files and OneDrive content. This setting determines if the AI can discover and list your files.

In the Permission settings section, locate the File search toggle. This controls file retrieval and indexing capabilities:

• Enable: Toggle ON to allow Copilot to search through your local files (.docx, .xlsx, .pptx, .txt, .pdf, .json) and OneDrive content
• Disable: Toggle OFF to prevent file discovery (default setting)

The setting applies immediately without requiring a restart.

Control whether Copilot can actually open and analyze the content of your files. This is separate from file search and provides deeper content access.

In the same Permission settings section, locate the File read toggle:

• Enable: Toggle ON to allow Copilot to read file contents for analysis and summarization
• Disable: Toggle OFF to prevent content reading while still allowing file discovery if search is enabled

Save your settings and verify the configuration is working as expected across different file types and locations.

Click the Back arrow to exit settings. Your changes are automatically saved and applied immediately. Test the configuration with these commands:

"Show me my recent Excel files"
"Find documents containing 'budget'"
"Summarize the content of my presentation files"

Based on your settings, Copilot should either fulfill these requests or explain that file access is disabled.

If you want to remove Copilot-related search icons from Windows interface while keeping the app functional, use this registry modification.

Open Registry Editor as administrator:

Win + R > regedit > Enter

Navigate to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search

Create or modify the DWORD value:

BingSearchEnabled = 0 (disable icons)
BingSearchEnabled = 1 (enable icons)

Alternatively, use Command Prompt as administrator:

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Search" /v BingSearchEnabled /t REG_DWORD /d 0 /f

For organizations or users who want to completely disable Copilot functionality system-wide, use this registry modification.

Open Registry Editor as administrator and navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsCopilot

If the path doesn't exist, create the keys manually. Create a DWORD value:

TurnOffWindowsCopilot = 1 (disable completely)
TurnOffWindowsCopilot = 0 (enable)

Using PowerShell as administrator:

New-Item -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsCopilot" -Force
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsCopilot" -Name "TurnOffWindowsCopilot" -Value 1 -Type DWord

Address frequent problems when configuring Copilot file search permissions and verify your setup is working correctly.

Settings not visible: Update Copilot app through Microsoft Store. Check app version:

Get-AppxPackage Microsoft.Copilot | Select-Object Version

Changes not applying: Restart Windows Explorer:

taskkill /f /im explorer.exe
start explorer.exe

Registry keys missing: Create them manually by right-clicking in Registry Editor and selecting New > Key or New > DWORD Value.

File access still blocked: Sign out and back into your Microsoft account in Copilot settings. Ensure OneDrive is properly synced if accessing cloud files.
