The worst I have done to an OS was mess with UXTheme stuff. Caused my OS to not boot up properly (I'd boot, but wouldn't get to the lock screen. Reinstalled Windows because fuck trying to find actual fix.

That and I also made C:\ as primary partition on my laptop once and when I rebooted, "BOOTMGR is missing". That I was able to recover from thanks to command prompt.

We all do things that're stupid. That's what makes us human. It's also how we learn.

OH MY GOD IVE DONE THIS LIKE 6 TIMES.

After a while, I learned to stop fucking with visual styles and themes.
