Windows 10: Changing DPI in a photo

I need to change the DPI in a photo that I copied from a website (of my boss). I have submitted it to a publication, but they declined using it because the DPI was less than 300. What program could I use to fix that?

Windows Photo Viewer Disable DPI Scaling (Slideshow High DPI problem)

When viewing a slideshow (fullscreen) (F11) with Windows photo viewer at 150% DPI Scaling on a 4K monitor only part of the image is shown! The DPI scaling should be ignored when fullscreen. Anyone knows how to fix this bug??

The strange thing is that with PNG and JPG images Photo Viewer starts with DPI scaling.

However when opening a BMP photo viewer starts without DPI scaling and full screen slideshow works fine.

So a better question would be how to always start photo viewer without DPI scaling.

Unfortunately it's a dll and compatibility settings are not available...
