Hardware-Accelerated BitLocker Encryption: Because Apparently Software Was Too Damn Slow

Right, so Microsoft’s gone and stuffed yet another shiny new “feature” into Windows 11, this time letting BitLocker use fancy hardware-based crypto engines built into modern SoCs. Basically, they’ve realised that making the CPU do encryption in software is eating cycles like a starving hippo, so they’re offloading the work to whatever silicon voodoo the chipmaker soldered onto the motherboard.

These SoC crypto engines are meant to handle all the number-crunching so your laptop doesn’t wheeze like an asthmatic hamster every time it encrypts a drive. Supposedly, this hardware wizardry means faster bootups, longer battery life, and maybe—just maybe—a PC that doesn’t spend its entire life at 99% CPU while pretending to protect your data.

Of course, there are a few “ifs,” “buts,” and “requires specific firmware” bullshit. Not all devices support it, and you’ll need Windows 11 that’s current enough to not be held together by duct tape. Microsoft put it in the “Device Encryption” setups mostly, meaning your shiny new Surface gets to enjoy it, and your five-year-old workhorse can go cry in the corner with software-based encryption like a loser. Typical.

When it works, Windows quietly flips over to using hardware acceleration automatically, no “press F8 and pray to the sysadmin gods” required. You can even use PowerShell and Event Viewer to check if it’s enabled because of course they couldn’t just, you know, add a friendly damn toggle or status screen. No, you’ve got to dig through command outputs and logs like an archaeologist with caffeine shakes.

So yeah, hardware-accelerated BitLocker: great for newer hardware, great for Microsoft’s PR, and one more “helpful improvement” that’ll leave the rest of us explaining to users why their old laptops still take half a bloody day to encrypt a drive.

Reminds me of the time a user demanded I “speed up” their encryption process. I told them I’d happily do so—right after they upgrade their ten-year-old laptop and stop using it as a damn space heater. They didn’t like that answer. I didn’t care. Typical day in the digital hellscape.
