In Windows 8, 8.1 and Windows 10, the default shutdown behavior puts the system into the hybrid shutdown state (S4), and all devices are put into D3. WOL from S4 or S5 is unsupported.

Network adapters are explicitly not armed for WOL in either S5 or S4 cases because users expect zero power consumption and battery drain in the shutdown state.

This behavior removes the possibility of invalid wake-ups when an explicit shutdown is requested.

Therefore, WOL is supported only from sleep (S3) or hibernation (S4) states in Windows 8, 8.1 and Windows 10.

In Windows 8, 8.1 and Windows 10, hybrid shutdown (S4) stops user sessions but lets the contents of kernel sessions be written to the hard disk.

This enables faster startups.

To disable the S4 state in Windows 8, 8.1 and Windows 10, follow these steps.

Note We do not recommend that you disable the hybrid shutdown (S4) state.

1. In Control Panel, open the Power Options item.

2. Click the Choose what the power buttons do link.

3. Clear the Turn on fast startup (recommended) check box.

4. Click Save Settings.
