Winlogon Wikipedia. This article needs to be updated. Please update this article to reflect recent events or newly available information. January 2. In computing, Winlogon is the component of Microsoft Windowsoperating systems that is responsible for handling the secure attention sequence, loading the user profile on logon, and optionally locking the computer when a screensaver is running requiring another authentication step.

Winlogon is a common target for several threats that could modify its function and memory usage. Increased memory usage for this process might indicate that it has been hijacked.

OvervieweditWinlogon handles interface functions that are independent of authentication policy. It creates the desktops for the window station, implements time out operations, and in versions of Windows prior to Windows Vista, provides a set of support functions for the GINA and takes responsibility for configuring machine and user Group Policy. Winlogon also checks if the copy of Windows is a legitimate license in Windows XP and later versions. Winlogon has the following responsibilities Window station and desktop protection. Winlogon sets the protection of the window station and corresponding desktops to ensure that each is properly accessible. In general, this means that the local system will have full access to these objects and that an interactively logged on user will have read access to the window station object and full access to the application desktop object. Winlogon has special hooks into the User. Control Alt Deletesecure attention sequence SAS events. Winlogon makes this SAS event information available to GINAs to use as their SAS, or as part of their SAS.

MS Paint, the first app you used for editing images, will probably be killed off in future updates of Windows 10, replaced by the new app Paint 3D. Microsoft lists. Emacs Speaks Statistics ESS provides an intelligent, consistent interface between the user and the software. ESS interfaces with SAS, SPLUS, R, BUGSJAGS and other. In general, GINAs should monitor SASs on their own however, any GINA that has the standard CtrlAltDel SAS as one of the SASs it recognizes should use the Winlogon support provided for this purpose. When Winlogon encounters a SAS event or when a SAS is delivered to Winlogon by the GINA, Winlogon sets the state accordingly, changes to the Winlogon desktop, and calls one of the SAS processing functions of the GINA. When users log on, their user profiles are loaded into the registry. In this way, the processes of the user can use the special registry key HKEYCURRENTUSER. Winlogon does this automatically after a successful logon but before activation of the shell for the newly logged on user. Assignment of security to user shell. When a user logs on, the GINA is responsible for creating one or more initial processes for that user. Winlogon provides a support function for the GINA to apply the security of the newly logged on user to these processes. However, the preferred way to do this is for the GINA to call the Windows function Create. Process. As. User, and let the system provide the service. Winlogon monitors keyboard and mouse activity to determine when to activate screen savers. After the screen saver is activated, Winlogon continues to monitor keyboard and mouse activity to determine when to terminate the screen saver. If the screen saver is marked as secure, Winlogon treats the workstation as locked. When there is mouse or keyboard activity, Winlogon invokes the Wlx. Display. Locked. Notice function of the GINA and locked workstation behavior resumes.

Multiple network provider support. Multiple networks installed on a Windows system can be included in the authentication process and in password updating operations. This inclusion lets additional networks gather identification and authentication information all at once during normal logon, using the secure desktop of Winlogon. Some of the parameters required in the Winlogon services available to GINAs explicitly support these additional network providers. See alsoeditExternal linksedit.
