Before we can use Fast Startup we need to make sure your computer is configured to Hibernate.

Press Windows Key + x + a to open a command prompt with Administrator privileges.

If you don’t have admin rights beg your IT person to enable Fast Startup for you.

If that doesn’t work, you can make a cogent case to your manager about how slow startup is having a corrosive effect on your productivity. Furthmore, make a passionate plea about how your slow machine leaves you disgruntled and is having a deleterious effect on your health.

If he or she simply gives you a dispassionate stare or flashes an incredulous brow raise – threaten to quit.  You don’t need to work in an environment like that.

hahaha, ok let me stop.

Enable hiberation with cmd

To enable hibernation type the following in the command prompt:

powercfg -h on

Enable hibernation: powercfg on

Enable Hybrid Boot

Next we need to open Regedit.

Make sure you backup the Registry first then type this into your command window:

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 1 /F

Enable Fast Startup from the CLI

I know this looks scary so let me break it down:


REG ADD is a neat utility that lets you modify the registry from the command line.

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power

This is tantamount to clicking Start, typing regedit and finding this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power

The REG ADD command modifies the key and changes the HiberbootEnabled DWORD to 1 in a single statement.

Concise and effective.

It also has the serendipitous effect of making you look cooler if someone walks by your desk while you’re using it.

Windows 8.1 Enable Hiberboot

After you make the registry change the effects should be immediate.

Now when you boot up your computer you should notice a substantive improvement in start up time.  Andif you have a UEFI enabled device it’ll be even faster.

Closing Thoughts

Fast Startup is great but it’s not the panecea for every slow startup woe.

In some cases it may have an adverse affect on your system.  For example, it can cause your computer to unceremoniously reboot when the Sign-in screen appears.  Also some people say Fast Startup causes the system to freeze on shutdown or startup.

Admittedly, this is more of a concern on computers that dual-boot Windows 8; however, I bring it up here because I want you to know that Fast Startup isn’t perfect.

If your computer is generally slow try deleting useless files and speeding up Firefox, Internet Explorer andChrome.  You can also go for a Solid State Drive, which will yield instant gratification.
