Where is the windows security button

At my institution, the Panasonic interenergetic "SmartBoard" present a different message on the Windows 7 login screen. Instead of:

Press CTRL + ALT + DELETE to log on

It reads:

Press CTRL + ALT + DELETE or usage the Windows Security Button to log on

What is this "Windows Security Button", and where is it located?


*

Control+ALT+Delete in PC hardware is the Secure Attention Sequence (SAS). The SAS is a hardware-produced non-maskable interrupt (NMI) that deserve to only be tackled by the kernel and also can not be suppressed (that"s what "secure" and also "non-maskable" expect.)

Windows have the right to usage this key-board combo to encertain that the user logging in is physically current and to make spoofed login displays automatically apparent to the user (because they can"t detect/respond to the sequence.)

Since an on-screen keyboard is software instead of hardware, it can not generate the SAS/NMI. The Windows Security Button gives this feature on tablets and also various other Windows gadgets which are not intfinished for use through a hardware keyboard.

Jhawins:

The Windows Security Button on many kind of Windows taballows is a hardware switch which when pressed has the very same result as initiating the secure attention sequence (i.e. pressing Ctrl+Alt+Delete).

I have had actually to allow this attribute on taballows at job-related to enable bypassing of the Ctrl-Alt-Del display screen without connecting a key-board. In our case (Acer Iconia) we had actually to host a distinct Windows essential on the bottom of the tablet and also push the power switch concurrently.

As the write-up linked to over says: not eexceptionally gadget has actually a designated "protection button".

If you don"t have actually a complete keyboard on your whiteboard, then I would assume it has some type of security switch to compensate- as via taballows. You deserve to probably work it out by trial and also error: allow the defense button feature, then log out and also go through all the buttons until somepoint unlocks it - or a combination of somepoint + power unlocks it.

I know this 3-vital combicountry is a defense attribute but it"s worth maintaining in mind that you can disable it very easily - causing it to go straight to the password prompt display screen instead.
