Hi @bilo_z,

Welcome to the HP Support Community.
 

I understand. If you have already uninstalled HP PC Hardware Diagnostics for Windows but the message still appears when you start the computer, we should first identify exactly which HP component or startup entry is generating it.
 

As a first check, please open Settings > Apps > Startup and see whether you still have an HP Diagnostics-related entry listed there. If you find one, please let us know the exact name shown. Windows also allows startup applications to be managed from Task Manager > Startup apps.
 

Please don't delete anything from the Windows Registry or remove any HP files manually yet. We want to make sure we identify the correct component before removing anything.
 

Also, could you please provide:

• Your exact HP PC model/product number
• The exact wording of the message that appears at startup
• A photo or screenshot of the message, if possible
• Whether the message appears before Windows starts or after you reach the Windows desktop

This distinction is important because HP PC Hardware Diagnostics for Windows runs within Windows, while HP PC Hardware Diagnostics UEFI runs outside the operating system.
 

Once we have the exact message and your HP product details, we can determine what is causing it and guide you through the appropriate way to remove it without affecting any required HP or Windows startup components.

Take care and have an amazing day!
