JSI Tip 0352 - When is Last Known Good set?

In tip 187 we learned how to prevent Last Known Good from being set and how to prevent a Last Known Good selection during boot.

Normally, Last Known Good is set when the first user logs on. If you set ReportBootOk to 0, you can run a boot verification service defined at:

HKEY_LOCAL_MACHINE\SYSTEM\all control sets\Services\BootVerify

or you can provide a program that sets ReportBootOk and define it at:

HKEY_LOCAL_MACHINE\SYSTEM\all control sets\Control\BootVerificationProgram\ImagePath

and enter the full path to your program in this type REG_SZ.

Check the SDK for details (don't ask us, we are not programmers).
