This has confused me. For a while I had every font changed within Windows, but the 1909 update reverted the Context Menu and Taskbar to the default Segoe. All other fonts can be changed except these. Even using WinAero Tweaker and registry edits it has no effect.

I have every font altered in WndowsMetrics registry and all the Segoe fonts changed in FontSubstitutes registry, it still has no effect.

It even ignores any changes to font smoothing turned off in Performance Options.

What confuses me even more is that I have another PC that also claims to be on 1909, yet the font is customized.
