When and why you should disable Fast Startup (fast boot) on Windows 10


Fast startup” sounds nice, doesn’t it?  Time is money, so therefore one would assume that faster is better.

Windows 10 includes a feature called Fast Startup which is enabled by default on most clean installations of Windows 10. Fast Startup essentially hibernates the Windows kernel and loaded drivers to help speed up startup times.

Not so great

Those hibernation can interfere with Windows Updates, making updates freeze.

Fast Startup also is known to cause problems with encrypted discs.

When running Windows from a SSD you really don’t notice a difference.

Dual boot

When you’ve installed both Windows and Linux on the same machine the NTFS hard discs are not completely shut down when hibernating Windows. Accessing such a hard disc from Linux can result in data loss and even disc corruption.  That’s the reason why some Linux distros like f.e. Ubuntu wont let you mount those NTFS devices in writeable mode as long as Fast Startup is enabled.

But even when you’re dual booting side by side Windows installations Fast Startup will increase (!) the startup time of both installed OS.

Turn Fast Startup On or Off

Microsoft has decided to hide the settings for Fast Startup deep inside the “current energy plan”.   After clicking 100 times with your mouse you’re there!

Or you use our free tool Fast Startup Switcher that only needs one single click.
