Windows 10 - System nicht ausschalten, nachdem Windows heruntergefahren wurde

[t.roller]

LOGO.SYS is in fact an 8-bit RLE-encoded Windows bitmap file with a resolution of exactly 320×400 pixels at 256 colors.

LOGO.SYS is a core system file used by Windows 9x operating systems to display its boot-up message.

It is present and used in the Windows 95, Windows 98, Windows 98 SE and Windows ME products. It is not present in the Windows NT family of operating systems, such as Windows XP.

LOGOS.SYS: the "It is now safe to turn off your computer" message. The file is located in the Windows directory. This message is displayed when Windows has successfully shut down to MS-DOS but is not configured to return to the prompt (COMMAND.COM) again.
On systems with proper ACPI support and ATX power supply, the PC may power down instead. If the file cannot be found, the same message is displayed in text mode. No error will be shown if the file cannot be found.
