Windows 8 Developer Preview was released during BUILD conference in September,2011 and lot of new features of Windows 8 were demonstrated at the conference. One such new feature introduced in Windows 8 is the 'Hybrid Boot'. The Hybrid Boot feature allows you to reduce start up time after shutting down Windows 8 computer. That is the reason why Windows 8 boots faster compared to Windows 7. This is a booting process which is in between Hibernation and normal cold boot. Normally in hibernation mode, all the files are saved in the same state, but in Hybrid boot mode, only the operating system files are saved in same state so that booting process does not take much time.
The Hybrid Boot is enabled by default in Windows 8 Developer Preview, but if you want to disable it or enable it ( if not enabled by default), it is possible to do it from Control Panel. Here is a step by step guide on how to enable or disable Hybrid Boot in Windows 8.
- First open Control Panel.
- Navigate to Hardware and Sound -> Power Options
- Click on "Choose what the power button does" on left hand side.
- Click on "Change settings that are currently unavailable" later on.
- Now you will see at the bottom an option "Enable Hybrid Boot" under Windows shutdown settings. From here you can either enable or disable Hybrid Boot by either checking or unchecking that check box option. When Hybrid Boot is enabled, Windows 8 does not close the kernel session, but closes just the user sessions.
If the Hybrid Boot option is disabled in Windows 8, it will revert back to classic shutdown behavior.
