Hi Livid_Tech,
Welcome to the Microsoft Q&A!
I'm sorry to hear that your Settings icon is missing from the taskbar, with many other icons missing from the imageres.dll. I understand how frustrating it can be when such a core app behaves inconsistently, especially after trying several advanced repair steps.
To assist you further, can you clarify your Windows version and if the problem started recently? Knowing that will help tailor the troubleshooting steps more precisely. As Windows 11 allows you to pin the Settings app, I will assume for now that you are using Windows 10 and provide suggestions based on that, if that's okay with you?
1 - Re-register the Settings App
- Open Windows PowerShell > Run as administrator > Copy and paste the following command:
Get-AppxPackage windows.immersivecontrolpanel | Foreach {
Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"
}
- Enter to re-link the Settings app with the system interface > restart your PC.
2 - Restart with Clean Boot:
Sometimes other applications are the ones messing with your Settings. If you can't pinpoint the exact problem, trying a clean boot can help rule out software conflicts.
- Find
msconfig> disable all non-Microsoft startup items/services > restart PC. - See if the problem persists. If not, it's likely that one of your downloaded apps was the cause.
- You may need to manually disable/enable one item after another to identify the offender, then consider removing or disabling it.
Disclaimer: A "clean boot" starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem. These steps might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step so that it will help you get back on track.
3 - Reset your access:
- Press Win + R > type in
regedit> Search following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows
- Right click Permissions > advanced > owner > edit > click on your username and then apply.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
4 - Check Group Policy (if possible)
- Run
gpedit.msc> Navigate to:
User Configuration > Administrative Templates > Start Menu and Taskbar
- Review settings that may block system app visibility or pinning
5 - Rebuild the Icon Cache:
