System
The following restrictions are available in this group:
- Restricting Access to the Event Logs - The Windows NT event log
contains records documenting application, security and system events taking
place on the machine. These logs can contain sensitive data, and by default,
the Guest account has access to view them. This tweak allows you to restrict
access to administrators and system accounts. Option affects the whole PC.
Reboot your PC to activate or deactivate this option. Applicable to Windows
NT/2000/XP.
- Stopping the KnownDLLs Vulnerability - In Windows NT the core
operating system DLLs are kept in virtual memory and shared between the
programs running on the system. This has exposed a vulnerability that could
allow a user to gain administrative privileges on the computer the user is
interactively logged onto. Option affects the whole PC. Reboot your PC to
activate or deactivate this option. Applicable to Windows NT/2000/XP.
- Clear the Page File at System Shutdown - Windows normally does not
clear or recreate the page file. On a heavy used system this can be both a
security threat and performance drop. Enabling this setting will cause Windows
to clear the page file whenever the system is shutdown. Option affects the
whole PC. Reboot your PC to activate or deactivate this option. Applicable to
Windows NT/2000/XP.
- Disable the Automatic Restarting of the Shell - By default if the
Windows user interface or one of its components fails, the interface is
restarted automatically, this can be changed so that you must restart the
interface by logging off and logging on again manually. Option affects the
whole PC. Reboot your PC to activate or deactivate this option. Applicable to
Windows NT/2000/XP.
- Disable Shutdown from Authentication Dialog Box - When this setting
is enabled a [Shutdown] button is not displayed in authentication dialog box
when the system first starts. This does not allow you to shutdown a system
without logging in. Option affects the whole PC. Reboot your PC to activate or
deactivate this option. Applicable to Windows NT.
- Disable Multiple User Sessions and Fast User Switching - By
default, Windows XP gives you an ability to switch between users without
logging off that keeps all active users on your PC with all started processes
and programs. On a heavy used system this can be both a security threat and
performance drop. This option disables multiple user sessions and fast user
switching on your PC. Option affects the whole PC. Reboot your PC to activate
or deactivate this option. Applicable to Windows XP.
