I had a user report a crash of a JUCE application that displayed the following message:

```auto
<appName>.exe!GetSystemMetricsForDpi

```

This user is on Windows 8.

Does anyone have any ideas?

That function needs at least Windows 10

I see. I don’t recall specifically enabling any kind of DPI features, does JUCE use them by default?

Does JUCE 8 still support Windows 8, or is Windows 10 the minimum requirement?

If you use JUCE 8, there is no way around that.

Ah. So does JUCE 8 require Windows 10?

Windows 10 is the minimum deployment target for JUCE 8.
