The Windows Features dialog box (
optionalfeatures.exe) lets you add or remove additional or optional Windows features. For instance, you can remove Media Features > Windows Media Player using “Turn Windows Features On Or Off ” dialog box if you no longer plan to use WMP.
Sometimes, the “Turn Windows Features On Or Off” listing may be empty.
If the list doesn’t populate even after waiting for several minutes, here is how to fix the problem.
Step 1 : Start the Windows Modules Installer service
1. Press WinKey + R to open the Run dialog
services.msc and press ENTER. This will open the Services console.
3. Double-click Windows Modules Installer service.
4. Set its Start type to to Automatic.
5. If the Windows Modules Installer service is not running, click the Start button to start it.
Step 2 : Run the System File Checker
The System File Checker is used to scan for missing system files and restore them.
1. Open an elevated Command Prompt window.
2. Type the following command and hit ENTER:
If SFC is unable to restore the missing or corrupt system files due to component store corruption, proceed to Step 3.
Step 3: Repair the Component Store using DISM
From the elevated Command Prompt window, type the following command:
DISM /Online /Cleanup-image /Restorehealth
Wait for the operation to complete. This command repairs the Component Store if any corruption is found.
Additional Tip: If the above doesn’t still help, you can run the DISM command mentioning the source image (fresh Windows 10 Install.wim) from the mounted ISO or DVD media matching the same Windows 10 build your system is running.

Hope that fixes the empty “Turn Windows Features on or off” listing issue.
