Windows update 1809 introduced new location for system fonts. Previously the fonts were installed in all-users location C:\Windows\Fonts, but in Windows update 1809 the fonts are installed in user specific location C:\Users\UserName\AppData\Local\Microsoft\Windows\Fonts. Now, Qt cannot find system fonts on systems with Windows update 1809.
Steps to reproduce:
- Install new font
- Query fonts with QFontDatabase::families() or use Qt's Font Sampler example.
- The newly installed font is not on the list
