There is (or at least used to be) a debug command to write-protect a hard drive. No idea what it’s for or why such a thing exists, but you flip a certain bit from 0 to 1 and drive no write. I won $100 once at work with this knowledge. We had a training course about how much better the new version of windows at the time was and how much harder it was to break - so hard they’d pay $100 (in early 2000s money) to anyone who could unrecoverably break their demo windows install during the 10 minute presentation. The instructor (who worked for Microsoft) said he’d been doing this for 6 months and they’d never had to pay out that prize before, much less 30 seconds in.
No, this was via debug, a command that’s been included in MS-DOS since like version 2.0 (before there even was a Windows, much less full-OS windows like Win95/NT/etc rather than 3.0/3.1 that were just fancy launchers that sat on top of DOS.) It can let you view and alter the contents of memory at a particular address, etc. We also used it to wipe hard drives by forcibly writing 0s to every block on the drive.
You could do stuff like that with the older DOS versions of Norton Utilities. I used to do fun stuff like set my friend’s files as the drive label. He thought I was basically a wizard.

Sounds like something registry editor related.
