Fast Startup vs. Fast Boot: What’s the Difference and Should You Disable Them?
AI-summarised brief · reviewed before publication
The article clarifies the distinction between Windows’ Fast Startup and UEFI Fast Boot, two features often conflated by users. Fast Startup, enabled by default in Windows 10 and 11, saves a hibernation image of the system’s current state during shutdown, allowing a quicker power‑on by bypassing a full boot sequence. UEFI Fast Boot, a BIOS setting, reduces or skips hardware initialization checks to accelerate the handoff to the operating system. While Fast Boot is generally safe, Fast Startup can retain drivers and apps in memory, leading to issues such as delayed USB device detection, failure to apply driver updates, or persistent glitches that only a full reboot can resolve. The piece outlines step‑by‑step instructions for disabling Fast Startup via the Control Panel’s power options.
