Remarks

Handling the registry in Windows Vista (and later)

Starting with Windows Vista, if the UAC mechanism is enabled, you must have administrator rights to write to the "HKEY_LOCAL_MACHINE\SOFTWARE" key.
If the user does not have the necessary rights, the UAC mechanism performs a redirection to "HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE". The purpose of this redirection is to ensure the compatibility of the applications. The keys written in this directory can be read by the application that has written them.
Reminder: when creating the executable, a manifest can be included in the executable so that administrator rights are granted to the application.
