The WLTrialStringWriteW function writes a custom string to the Registry. The string is stored using encryption algorithms and the location of the string is different for each computer.
The location of the string also depends on the "Trial Unique Key" in the protected software. If you change the "Trial Unique Key" in your Software and protect again, the strings will be stored in a different Registry location.
NOTE: If StringName starts with "!", the custom string will be stored under HKEY_LOCAL_MACHINE, otherwise it will be stored under HKEY_CURRENT_USER in the Windows Registry.
