How to mask out information on the lock screen

Windows 8 can display information from some apps in the form of individually confi gurable notifi cations on the lock screen. But that may not be desirable if your system is used by more than one person. However, you can set the notifi cations to be invisible to some users and even prevent them from changing the settings for the same
by adding a few entries to the Windows registry.To do this, switch to Desktop view and use the key combination [Windows]+[R].
Then, type in “regedit”, press the [Enter] key and confirm the user account control dialogue box with “Yes” . Once the
registry editor opens, navigate to the key
“HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem”, click in the right-hand section of the window
and create a new entry by clicking “Edit | New | DWORDValue”. Name the new entry “DisableLockScreenAppNotifications” and
double-click on it to open it for editing. Change the value to “1” and confirm that with “OK”. Now close the registry editor and restart the system. There will be no more notifications displayed on the lock screen. If you wish to activate notifications again, set the registry value for the same entry to “0”.
