How to Dramatically Cut Your Windows 10 PC’s Boot Time

  • MORE

If you're tired of waiting and waiting for your Windows 10 PC to boot, you're going to want to make sure the Fast Startup setting is enabled. Also known as Fast Boot in Windows 8, this feature shuts your PC down similar to how it sets the machine to sleep, writing the state of your operating system to a hibernation file.

We tried this out on a PC we're currently testing for review, and enabling Fast Startup reduced our boot time from 1 minute to 19 seconds, shaving 41 seconds — two-thirds of the boot time — off. Since changing this setting doesn't take much time, why not take a moment now to save many in the future?

Users who encrypt their have drive with software like TrueCrypt may not want to enable the setting, as they will then need to manually dismount encrypted drives prior to shutting down. Fast Startup also may lead to file corruption or other issues for computers that dual-boot between partitions or operating systems, so keep the setting disabled if you manage your computer in that manner.

This setting is commonly enabled in PCs sold running Windows 10 and any that were upgraded from Windows 8, but it's more likely to be disabled on devices that were upgraded from Windows 7. Here are step-by-step instructions for how to turn on Fast Startup mode.

    My HP Elite laptop running Windows 10 also had the issue with very slow start up from sleep mode. Got worse with more Windows updates. I tried the various suggestions found on the internet including “fast startup” which was already selected as well as trying different sleep settings, no improvements. So in desperation I went to the settings dealing with what happens when I close the lid. I changed the lid settings to “do nothing” when I close the lid both for on-power and on-battery conditions. Now after closing the lid, the laptop still goes to sleep after the timeout set under Power and Sleep options (& requires me to log on with my password) but it wakes up much faster after I log in. Another benefit is that if I open the lid before the sleep timer has timed-out, the laptop pops up where I left off. Not sure why changing the lid action had such an impact on the laptop waking up but it sure worked for me.

    But fast startup is like 1/2 hibernate. It just shutdown the main pc but not the windows system. So better disable fast startup.

    I found that on fast PCs with SSDs, this setting actually slows down booting. The best thing to get a computer to boot in 8-17 seconds is to disable Fastboot, deactivate deep sleep hibernate and delete the hibernation file and make sure the PC is booting UEFI and of course no crapware installed.
