How do I get rid of this error popup?

So, I’ve got this laptop running Windows 7, and every time I boot it up, this annoying error window pops up regarding the hard drive. It keeps popping up again while I'm actually working, too. The laptop itself seems to be functioning just fine—no crashes or anything—but that constant pop-up is really starting to get under my skin.
I managed to find here some instructions on how to make that window go away. I followed everything step-by-step—specifically the parts meant for Windows 7—but for some reason, the error just keeps appearing regardless.
Does anyone happen to know a way to finally get rid of this thing?

Since Windows itself is throwing out these errors, it’s a pretty clear sign that your hard drive is acting up—and honestly, it’s a bit nerve-wracking to read about. If you have important files or photos saved there, you should probably grab a backup right away. You don't want to wake up one day to find you can't even boot into Windows and your data is totally out of reach.

The issue really seems to be rooted in the hardware. If you want to see what's actually going on under the hood, try downloading this little utility. Just take a screenshot of the results and post it here on the forum so we can take a look together...

Go ahead and grab the Standard Edition—it’s a tiny file, only about 3.8MB, so it shouldn't take long at all.

Honestly, I wouldn't be too worried if the hard drive gives up the ghost—I don't have any precious data stored on there anyway. It’s really just a spare laptop that I use for a few specific things:
-browsing the web
-Skype chats
-checking my email
...and that's pretty much it.
So, really, my only real concern is just making sure that window stops jumping around so much.

Maybe you just can't toggle that setting off because it's basically baked into the macOS "factory" defaults—how should I put this?—so if there’s an issue with the hard drive, the system is forced to flag it. I mean, once you're looking at a machine without a working hard drive, you're pretty much stuck, right? 🙂
