SecureUxTheme is a useful utility that removes signature verification of styles from Windows.
The software doesn’t modify system files and needs driver for running. However, this Secure boot compatible application edits format-wise valid signature. But a tool to fix styles with or without invalid one is included in the installer.
As said on Github SecureUxTheme is the only software to enable custom themes. The utility does never make any actual visual changes. This application is compatible with Windows 8.1,Windows 10 1507, Windows 10 1511 (untested), Windows 10 1607, Windows 10 1703 (untested), Windows 10 1703 (untested), Windows 10 1709 (untested), Windows 10 1803 (untested), Windows 10 1809, and Windows 10 1903.
