On two systems I've tested, it makes minimal difference to the time of shut down and start up. I myself leave it enabled as it hasn't caused any issues or prevented me from entering the BIOS (UEFI).īut equally there's really no need or benefit in leaving it enabled. In short for the novice I'd leave it alone. During the discussion of Meltdown and Spectre it was suggested that a hard reboot might be safer.Īnd it's not like the system is consuming electricity when you 'false' shutdown anyway. Personally unless you're experiencing boot issues, have a specific need, or are running an old system where 10 may struggle anyway there's really no need to disable fast startup.īut equally there's really no need or benefit in leaving it enabled. On my Skylake desktop, that adds only a second or two on a boot. Then a shutdown always does a full cold boot.

I also found that I had to disable it so I could mount NTFS from dual-boot Linux.Īs the others say (and see the links posted by ADMint for the full story), but for the short story, go to:Ĭontrol Panel -> Power Options -> Choose what the power buttons doĪnd click 'Change settings that are currently unavailable' In any case, it's a feature that is totally unnecessary if you have SSD. Windows 8 called this fast boot or hybrid shutdown, and Windows 10 calls it fast startup, but I believe it is the same thing. Last post by Simon in this long running thread: Most likely during real shutdown, the system cannot be restarted even for Windows update. We discussed this some time back, and as I recall, never came to a conclusion as to what was and was not possible during sleep, hibernation, or fake shutdown. So unless the “fast startup” feature is manually shut off (its' on by default) you're vulnerable? I've read you should fully shut down your computer when not using for more than an hour and over night in light of Spectre/Meltdown.
