UxTheme service hook - Visual Theme Signature Bypass
I just had a little bit of free time, so I extracted some older code from Aero Glass for Win8 into the separate DLL to make it work on Windows 8.1.
It has not been tested, but you can play with this as you want, there is no limit. But also no support and probably no future development, because there is nothing more to change on it. Either It works or it does not work
How to install?
The only possible way to install it is using old injection method via AppInit_DLLs registry key.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows -> set AppInit_DLLs value to specific DLL for your OS (so select either xxx32.dll or xxx64.dll only!)
Although, it is not needed to make this work, it is also suitable that, on 64-bit Windows, you do the same "install" procedure on HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows (but always with xxx32.dll!). If you don't do this, 32-bit theme-related applications won't be able to access your unsigned themes.
Something to know?
Yes! There is one very important thing if you use Aero Glass for Win8.1! Due to certain DbgHelp.dll restriction, Aero Glass for Win8.1 won't able to load PDB symbols after you install UxThemeSignatureBypass.dll into your system. There is a simple workaround - just copy symsrv.dll from Aero Glass directory into your system directory (probably C:\Windows\System32). I will try to bring a fix for this in future version of Aero Glass for Win8.1, but I cannot promise that, because its a bit complicated.
License?
It's freeware. Use as you want, just the copyright must be preserved.
