hi
First, the API tht restarts windows is ExitWindowsEx defined in user32 library.
Second, AS FAR AS I CAN RECALL, the GUID (globaly unique identifier) is a 128-bit number, so it can take up to
2^(128) unique number, u do the math :), and it is usefull in case u need to merge two distant databases into one database, while insuring no conflict occures due to repeating id, so u use guids as ur primary key.
hope this helps.
