Run program at windows start
Run key (machine) Programs listed in the registry’s
HKLM\Software\Microsoft\Windows\CurrentVersion\Run key are available at
startup to all users.
Run key (user) Programs listed in the HKCU\Software\Microsoft\Windows\CurrentVersion\Run key run when the current user logs on. A similar subkey, HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows\Run, can also be used.
Load value Programs listed in the Load value of the registry key HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows run when any user logs on.
Scheduled tasks The Windows task scheduler (see “Using the Windows 7 Task Scheduler” on page 779) can specify tasks that run at startup. In addition, an administrator can set up tasks for your computer to run at startup that are not available for you to change or delete.
Win.ini Programs written for 16-bit Windows versions can add commands to the Load= and Run= lines in the [Windows] section of this startup file, which is located in %SystemRoot%. The Win.ini file is a legacy of the Windows 3.1 era.
RunOnce and RunOnceEx keys This group of registry keys identifies programs that run only once, at startup. These keys can be assigned to a specific user account or to the machine:
RunServices and RunServicesOnce keys As the names suggest, these rarely used keys can control automatic startup of services. They can be assigned to a specific user account or to a computer.
Winlogon key The Winlogon key controls actions that occur when you log on to a computer running Windows 7. Most of these actions are under the control of the operating system, but you can also add custom actions here. The “HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Userinit” and “HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell” subkeys can automatically launch programs.
Group Policy The Group Policy console includes two policies (one in Computer Configuration\Administrative Templates\System\Logon, and one in the comparable User Configuration folder) called Run These Programs At User Logon that specify a list of programs to be run whenever any user logs on.
Policies\Explorer\Run keys Using policy settings to specify startup programs, as described in the previous paragraph, creates corresponding values in either of two registry keys: HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run or HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run.
BootExecute value By default, the multistring BootExecute value of the registry key HKLM\System\CurrentControlSet\Control\Session Manager is set to autocheck autochk *. This value causes Windows, at startup, to check the file-system integrity of your hard disks if your system has been shut down abnormally. It is possible for other programs or processes to add themselves to this registry value. (Note: Microsoft warns against deleting the default BootExecute value.
Shell service objects Windows loads a number of helper dynamic-link libraries (DLLs) to add capabilities to the Windows shell.
Logon scripts Logon scripts, which run automatically at startup, can open other programs. Logon scripts are specified in Group Policy in Computer Configuration\Windows Settings\Scripts (Startup/Shutdown) and User Configuration\Windows Settings\Scripts (Logon/Logoff).
