Guide does use one registry value for Windows 10 users. It is used to disable themes. The toolbar in Guide will not display properly without themes disabled although it will work. The entry is under

\HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

There should be a registry string (REG_SZ) named C:\guide9\guide9.exe set to DISABLETHEMES. The name of the key will depend on where you have Guide loaded. The registry string can be modified or added using REGEDIT.
