Killing all of the wake timers and editing specific keys in the registry will usually fix this, but it's messy and not something typical users are comfortable doing.
This. During lockdowns, I dusted off an old PC and set it up with windows for gaming. The computer was in front of my bed. One out of two nights, the thing would randomly wake out of hibernation, blasting the freaking blue bitlocker screen at me (password unlock, since that PC didn't have a tpm).
This PC was kept reasonably up to date, too (usually installed whatever update at the most a day or two after they came out, complete with the reboot), so not sure what it was hoping to do, exactly.

I'm sure you mistakenly used sleep instead of hibernate without knowing or remembering, to have that issue, or you had the issue where hibernate didn't work and reverted to sleep instead.
I also had that issue and discovered that the Linux dual-boot installation with Grub's changes to the MBR broke Window's capability to hibernate, so me hitting hibernate was actually triggering sleep instead.
The USB bus and sound system is still the weak spot on a windows computer in my experience, this website, reddit, youtube, or dailymail generally takes them out.
Surprised that people used sleep and hibernate, considering TSR's were invented in the dos days and the browser can do lots of fancy stuff.
Theres even a reg setting to clear the page file on shutdown.
He means Windows can set a timer to wake up after a while to run scheduled tasks. You might not have noticed those wake timers because they are few and it usually works as expected with windows hibernating back after a few minutes.
The difficulty of disabling wake timers has been exaggerated, though. It's in the advanced power settings, there's no need for the big scary registry.

Yes, it can se timer to wake automatically from hibernate, but that doesn't mean it does that automatically withotu you setting those timers. I can understand there have been some bugs in the past but that's anon-issue today.
In hibernate the laptop stays powered off and nothing is running, you can even pull the power cord. It can't wake up from that. It will only wake up when you power it back on, not by itself. The wake up issues are for sleep mode, not hibernate where the CPU is completely off and unpowered.
