Well, without knowing the answer, I'd say your machine
needs "vision". Your desktop would at least need a webcam.
Or alternately, if you have a point&shoot digital camera,
you could take a picture of the offensive QR code, and
load that into your computer.

Then the next job, is getting a program to orient the
picture so it can be decoded, then convert it into
a URL for you.

https://www.nextofwindows.com/how-to-scan-qr-code-on-your-pc

So for fun, I took the picture of a QR code from that sample
article (cropped it in GIMP so just the QR squares were
in the picture), and uploaded it here.

https://webqr.com/

And that site gave back a URL of "http://en.m.wikipedia.org".

That means you don't even need a resident Win32 program
on your PC. You can also upload the image of the QR to
a web site and the web site can decode it for you. And
out comes a URL. Or other textual info.
