Every time the Windows 11 system runs an EXE file, a prompt box pops up. I want to close it.

That prompt is most likely the User Account Control (UAC) security feature in Windows 11. It appears whenever you run an EXE that requires elevated permissions. While you can disable or lower UAC prompts through Control Panel > User Accounts > Change User Account Control settings, I’d strongly caution against completely turning it off since it helps protect your system from malicious software.

A safer option is to:

Only lower the UAC setting one notch so you’re not prompted as often.

Add trusted apps to run at startup with elevated permissions using Task Scheduler.

Right-click > Properties > Compatibility tab > check Run this program as administrator for apps you trust.

This way, you reduce interruptions without fully removing an important layer of security.
