How To Turn Off Fast Startup in Windows 10
Fast Startup in Windows 10 is kinda like a semi-hibernate mode that speeds up boot times by saving certain system info before shutdown. On paper, it’s handy, but it can be a nightmare if you’re dealing with dual-boot setups, SSDs, or strange driver glitches. Sometimes, it blocks external drives from mounting properly or causes weird shutdowns. So, if Windows seems sluggish or you’re troubleshooting boot issues, turning this off might actually help speed things up and prevent conflicts.
How to Disable Fast Startup in Windows 10 via Command Line
Method 1: Use Command Prompt or PowerShell with Admin Rights
The quickest way is through terminal commands because it skips the GUI nonsense. Just open Command Prompt (Admin) or Windows PowerShell (Admin). To get there, hit Win + X and pick from the menu. If Command Prompt isn’t there, PowerShell works just as well. Then, type:
powercfg /hibernate off
This command disables hibernation first, which is directly tied to Fast Startup. Disabling hibernation effectively turns off Fast Startup, because Windows isn’t saving that hibernate image anymore. Expect a little popup or no response, but once it’s done, restart to see if it helped. Funny thing is, on some setups, it takes a reboot or two before the system actually clears out the cache and boots faster.
Other useful PowerCFG commands
If later, you change your mind and want Fast Startup back, just run:
powercfg /hibernate on
And if you wanna be more specific with hibernation modes, like reduced or full, you could try:
powercfg /hibernate /type reduced
powercfg /hibernate /type full
But honestly, just turning off hibernate does the trick. Keep in mind, these commands can sometimes be flaky if you have certain custom power profiles or third-party shutdown tools, so a reboot might be needed after running them.
How to Disable Fast Startup through the Registry
Method 2: Tweak it directly in the Registry (for the brave or desperate)
This one’s more involved, but if the command line feels too sleight-of-hand, messing with the registry is an option. Just hit Win + R, type regedit, and hit Enter. Be careful—this sorta editing can mess things up if you’re not paying attention. Then navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
Look for a key called HibernateEnabled. Double-click it, and you’ll see a value data box. Change it between 0 and 1:
- 0 = Fast Startup disabled
- 1 = Fast Startup enabled
Save and exit. Then, do a reboot. Sometimes, this method doesn’t work on Windows 10 updates without permissions — so, run the registry editor as administrator, and be ready to undo if something weird happens.
Alternative Method: Turn Off Fast Startup through Control Panel
If you’re more into clicking around than hacking registry files, this is your best shot. Go to Start > Control Panel > Power Options. Click on Choose what the power buttons do on the left sidebar. Hit Change settings that are currently unavailable (yes, admin rights needed).Then, under Shutdown settings, uncheck Turn on Fast Startup (recommended). Save, and restart. Sometimes, this doesn’t stick on Windows 10, especially if you’ve got some weird power settings or third-party tweaking tools, but it’s usually reliable.
Should You Disable Fast Startup?
Disable it if:
- You’re running a dual-boot system with Linux or another OS.
- Boots hang or external drives don’t show up properly after reboot.
- Having quirky driver or update problems.
- You’re rocking an SSD and don’t see the point of Fast Startup anymore.
Keep it on if:
- You’re still on HDDs — it helps drop boot time noticeably.
- You don’t run into any shutdown or driver headaches.
In the end, Fast Startup was kinda meant for older mechanical drives; with SSDs, it’s usually not worth the hassle. If boot issues are bugging the system, disabling Fast Startup might land you a more predictable startup. Or at least, that’s what some folks swear by.
