Certain versions of Windows starting with 8 have code for a SecureBoot watermark, which is usually hidden in normal circumstances, even if SecureBoot is off. It can be forcefully enabled by making a function (CDesktopWatermark::s_IsRetailReady) return false.
It may not work with all versions of Windows.
Tested on:
1703 (Windhawk Mod) - worked fine
1803 (shell32.dll patch) - worked fine
1809 (Windhawk Mod) - worked fine
21H2 (Windhawk Mod) - the watermark enabled but the warning wasn't there - missing text resources?
