Fast Startup is a feature in Windows 8 and 10, which speeds up the boot process significantly. With the Fast Startup feature enabled by default, when the user shuts down the computer, what happens under the hood is a hybrid shutdown sequence.<\/p>\n

When a user issues the shutdown command, all user accounts are logged off completely. Then the system hibernates at this point — writing the OS kernel image and loaded drivers to the hiberfil.sys file, located in the root of your system drive (typically C:).<\/p>\n

Powering on the computer again would cause the hiberfile to be loaded, restoring the previously saved image of the Windows kernel and loaded drivers. That’s how the Fast Startup works. This way, boot ups are faster when compared to the traditional shutdown & cold startup.<\/p>\n

Hiberfile (hiberfil.sys) type can be set to “Full” or “Reduced.” In “Full” mode (default setting), the hiberfile size would be 40% of the total physical memory.<\/p>\n

Note: In Windows 7, the hibernation file’s default size equals 75% of the total physical memory.<\/p>\n

\"reduced
Total Physical Memory – 7.9 GB<\/figcaption><\/figure>\n
\"reduced
Full Hiberfile size – 40% of 7.9 GB<\/figcaption><\/figure>\n

Whereas in Reduced mode, hiberfile consumes disk space that equals to only 20% of the RAM<\/strong>.<\/p>\n

The reduced<\/strong> mode is sufficient if you need the hiberboot (Fast Startup) feature but don’t need the (full) hibernate and the hybrid sleep features; you can use the (S1-S3) sleep feature though. It helps to set hiberfile to “Reduced” if you’re running short of disk space on the system drive.<\/p>\n\n\n\n\n\n

Set Hiberfile type to Reduced or Full, using Powercfg<\/h2>\n

Reduced mode<\/h3>\n

Open an elevated Command Prompt<\/a> window. Type the following command and press ENTER.<\/p>\n

powercfg \/h \/type reduced<\/pre>\n

You won’t be able to manually put your system to Hibernate mode when hiberfile type is set to Reduced — the “Hibernate” command<\/a> wouldn’t even show up in the Start as well as in the Win + X menu.<\/p>\n
Additionally, the hybrid sleep option would be disabled. You won’t see the setting in Power Options dialog, as well:<\/p>\n
\"hybrid

Now, if you run the powercfg.exe \/a<\/code> command-line to view the available power states for that computer, you’ll see this:<\/p>\n
\n
The following sleep states are available on this system:\r\n\r\nStandby (S3)\r\nFast Startup\r\n\r\nThe following sleep states are not available on this system:\r\nStandby (S1)\r\nThe system firmware does not support this standby state.\r\n\r\nStandby (S2)\r\nThe system firmware does not support this standby state.\r\n\r\nHibernate\r\nThe hiberfile type does not support hibernation.\r\n\r\nStandby (S0 Low Power Idle)\r\nThe system firmware does not support this standby state.\r\n\r\nHybrid Sleep\r\nHibernation is not available.<\/pre>\n<\/div>\n
Full mode<\/h3>\n
If you later decide to revert to the default setting, which is Full, use this command:<\/p>\n
powercfg \/h \/type full<\/pre>\n
The above command enables hibernation and hybrid sleep features.<\/p>\n

Running the powercfg.exe \/a<\/code> command-line now, shows the following:<\/p>\n
