The Windows registry includes the following four Run and RunOnce keys: If more than one program is registered under any particular key, the order in which those programs run is indeterminate. You can write multiple entries under a key. Register programs to run by adding entries of the form description- string= commandline. The data value for a key is a command line no longer than 260 characters.
Run and RunOnce registry keys cause programs to run each time a user logs on.
