Hi M M Hasan,
Thanks for reaching out to Microsoft Q&A Forum. I understand that you are seeing the “Microsoft (R) HTML Application Host” process repeatedly running after startup and would like to know why this behavior occurs.
Before moving forward, could you please help clarify the following:
- Can you confirm whether the affected system is Windows 11 Pro for home/personal use, or is it Windows Server (for example, Windows Server 2022)?
- Is this device managed in a work or organization environment, or is it a standalone personal PC?
