NVDA menu » Tools » Run COM Registration fixing tool

Actual behavior:

Quotes from @Qchristensen here in issue #10791:

The only other dialog I couldn't close with alt+f4 was the "Run COM Registration fixing tool", which can't be closed with alt+f4, or escape, you need to activate either the Yes or No button […]

The question the dialog proposes is:

You are about to run the COM Registration Fixing tool. This tool will try to fix common system problems that stop NVDA from being able to access content in many programs including Firefox and Internet Explorer. This tool must make changes to the System registry and therefore requires administrative access. Are you sure you wish to proceed?"

It requires an explicit yes / no answer.

Expected behavior:

[…] (ideally, ALT+F4, and escape, should both activate the no button on that dialog).
