Unlock a Win 7 Machine

[Steve21]

Give it a try and let us know what you think of it.

 

I think trying to get someone to pay $40 for a piece of software that won't even work with Win7 , and that does what XP already lets you do is rather stupid... but then I guess its your software from your posts?

Perhaps AdmnGurl could integrate SasLibEx to make her program compatible with modern OSs?

 

Existing code to simulate the Secure Attention Sequence (SAS),which most people refer to as control alt delete or ctrl-alt-del, no longer works in Windows Vista. It seems that Microsoft offers a library that exports a function called SimulateSAS(). It is not public and one is supposed to request it by sending a mail to [email protected]. Mails to this address remain unanswered though.

 

I researched how other people (including Microsoft) have solved this task and was unhappy with the results: some solutions work only with (or without) UAC, most solutions work only for the current or console Terminal Server sessions or need a kernel mode driver.

 

So I decided to create my own Saslib with the following goals:

 

• Should work both with and without User Account Control (UAC)
  
• Should support current, console and any Terminal Server session
  
• Does not need a driver
  
• The calling application does not need to be signed or have a special manifest
  
• Support multiple programming languages
  

I have succeeded and thus SasLibEx was born: not only can it successfully simulate the SAS sequence it can do this for any/all Terminal Server sessions. It can also lock the workstation (again for all sessions) and switch between the normal desktop and the secure desktop (the desktop that UAC runs on). SasLibEx was successfully tested both with and without User Account Control (UAC).

It is quite a frustrating thing this problem, in our school we cannot run fast user switching either, so we basically have to disable workstation locking for all the pupils on the school now that we are migrating to windows 7 to prevent them locking off computers and just leaving the classrooms, I cannot understand M$ logic behind removing that function of allowing an admin to log off a user.

I would have disabled locking for students from the get go!

Out of interest, why?

[rich_tech]

I don't believe that we cannot, I think that we do not because we don't want multiple users logging onto the PCs endlessly now and its always been set to off historically on our network, areas like our library were a favourite for people locking workstations and going off to class.

 

We have impero in place though which helps us with the logging people off if need be, but obviously we need to log onto another PC then to log them off, whereas with XP one logon and it logged them off.

Also with Impero v3 can unlock the screen with logging them out but of course need to run Impero to do it so still need to login into a machine etc..

Some guy posts a YouTube video, provides no source code, no demo and your believe the guy can actually do this stuff??

 

Has anybody actually used this library or seen it used anywhere buy on a YouTube video?

 

The video is a great only if you want a good laugh!

We use a little hta script that sends a remote logoff command to the workstation if a teacher decides to lock it and not come back.

 

Works very nicely

[mrb-solutions]

So im guessing noone has come up with anything other than running a command from a different computer?

 

The problem i have is that i come across this problem at the other end of the school from my computer and would be very useful if we had something that could unlock or log off the user so that someone else could log on instead as our teachers tend to leave their computers locked rather than logging off, the next teacher that comes to teach then has to turn pc off and on before they can use.

[Boredguy]

Unless you have fast user switching enabled (which most people don't), the only other way is to use a different machine.

 

If we're away from our desk when we find a locked PC, we just logon to the nearest free computer to run the script.

I'm sure if we had enough time, we could even get it to unlock via our phones as long as we went to a webpage that could run the WMI command to logoff.

Hasn't this just been discussed recently in this thread here, with a solution that actually works??
