We are developing a software for a hosting company. This software is required to Lock/Unlock computers based on whether the admin is physically present or not.  We are using RFID. So as long as the software detects admin's RFID, the system remains unlocked. As soon as the Admin leaves the premises, the software automatically locks the computer. Untill the admin again enters the premises.  The main problem in getting this to work is, the application needs to run at all time and no one should be able to close the application.  Even if it shows up in task manager, the main purpose is the no one should be able to close the application.

I have a requirement to hide a process in Task Manager. It is for Intranet scenario. So, everything is legitimate. :)   Please feel free to share any code you have (preferably in C#) or any other techniques or any issues in going with this route.  Update1: Most of the users have admin privileges in order to run some legacy apps. So, one of the suggestion was to hide it in task manager. If there are other approaches to prevent users from killing the process, that would be great.  Update2: Removing the reference to rootkit. Somehow made this post look negative.

I sometimes have long running processes that I want to kick off before going home, so I create a SSH session to the server to start the process, but then I want to close my laptop and go home and later, after dinner, I want to check on the process that I started before leaving work. How can I do that with SSH? My understanding is that if you break your SSH connection you will also break your login session on the server, therefore killing the long running process.

I want to limit access to running apps with a password. Is that possible? I have an app in the tray icon and I want to close it for unauthorized access.  Greetings

Windows has a slide-away lock screen, as is common for mobile operating systems designed for a touch interface, to prevent accidental input. On a desktop PC, laptop without a touch screen, or laptop for which accidental touches are unlikely (like a clamshell), this is just an extra unnecessary step before logging in. The option to disable the lock screen will disable the entire lock screen, including the password requirement, which is not always desirable.  While a keypress will dismiss this screen, there is a delay after that keypress before the password box becomes editable, so you can't just type "spacebar[password]" to log in. The first character or so of your password may be lost depending on your typing speed.  Is there a way to disable the swipe away screen, and have Windows wake up directly to the password/login screen?

There is a very bad problem with the "Blank screen" function in Ubuntu 17.10. I refer to the setting accessed via Settings->Power->Blank Screen. This seems to actually perform a screen lock, since I need to enter my password after un-blanking the screen. (However, given the behavior described below it's not clear exactly what this function actually does - maybe it just logs you out? maybe it reboots the machine?)  The problem is that a simple screen lock, which one would expect to lock the screen without affecting the state of any applications, in fact closes all applications that are open when the screen lock activates. In other words, if you have the screen lock set to 5 minutes, and you walk away from your machine to get a sandwich or whatever, when you come back and unlock the machine all your apps have closed without saving their state. So far, the only work-around I have found is to entirely disable screen locking in Ubuntu 17.10. My question is, how can this be fixed so that screen locking works properly - that is: the screen locks on schedule after a period of inactivity, and when unlocked all applications that were running are still running?  I am asking a new question for the following reasons:  1) The existing answers to (and comments on)  do not address the issue, and in fact misrepresent the actual problem in ways that make me think the comment writers have not understood what is happening;  2) I cannot usefully address that question because I do not have sufficient reputation to either upvote the question or comment on it, and I cannot answer the question because I have no idea why this problem occurs;  3) I will probably never achieve a reputation of 15, much less 50, on StackExchange. Which is fine, that's not among my life goals.  4) But this question is important and deserves to be addressed. It is a drastically unacceptable bug.

I want to configure Windows 7 to login automatically after the computer is switched on. That's not because I'm lazy and don't like typing passwords. That's because I want programs that are configured to run on startup run automatically.  But I don't want everyone to see my desktop, so I want my computer to remain locked. When I'm ready to work, I just type my password and don't have to wait until all startup programs run.

If I'm logged into a remote Linux machine, I know I can suspend a process (cntr-z) and move it to the background (bg 1) but if I disconnect from the machine, the process stops.  Is there a way I can leave it in the background and have it there when I log back in? This is a very long running process.  On Ubuntu, logged in via SSH.

The difficulty is that it should be cross platform. Windows 2000, XP, Vista, OSX, Linux, other unix variants. I am looking for a snippet of code that can accomplish this for all platforms, and a way to detect the platform.  Now, you should be aware of  that user.home does not work correctly, so please do not provide me of textbook answers, I can find these myself in the manuals.

I'm working on re-purposing a Win10 laptop that has some security feature whereby all USB disks have to be approved and registered. I cannot remove that feature because I cannot see which app, service or setting is doing it. When I plug in a USB disk I get a pop-up saying the disk is not registered and cannot be used etc. The pop-up just sits there. I open Task Manager and it just has those zillion processes running. None of their names or resource usage patterns tips me off as the process that is displaying that pop-up. If I press alt-tab it just shows that pop-up as one of the running Apps but no indication of the name or location of any of the Apps. If there's visibly a Window opened up on your desktop is there a way to track down which App owns or opened that Window?  BTW it's not a browser or browser notification.  It has to be some kind of background security SW. A friend of mine was gifted her work laptop when she got laid off with the caveat that it was strictly as is. The thing is like Fort Knox and I've been unraveling all their security stuff. But I cannot find the origin or enforcer of this USB limitation.

Is there a way to lock a Windows XP machine via the command line?  The shutdown command doesn't have an option for it.

I want to restrict an application being opened under ordinary privileges. Only root shall run the application, so that contents wont be seen by others and they wont change anything.

I was wondering if I could keep program A from reading my entire ram, as it does not need to monitor what program B is doing.  Also I am on windows 8.1 64 bit.

The statement: "You must activate windows within 3 days to continue using all windows features." often pops up in my notifification area on Windows 7.  My windows are legal and I have activated them twice allready. I believe that windows remembers hardware of computer during last activation and shows this warning everytime it detects hardware change.  In my case detected hardware changes are probably caused by running windows from VirtualBox. I have dual boot setup. I can boot to both windows 7 and linux. When I want to use some Windows feature in linux I don't reboot the computer but start my windows 7 from VirtualBox which uses the raw disk insted of virtual one.  I hope that you can tell me which hardware change causes the activation request so i can do something about the popup message.

I've recently installed Ubuntu 18.04 in a dual-boot configuration with Windows 10. I noticed today that, when trying to open system settings, Ubuntu seems to log me out to the lock screen. When I log back in, all previously-running applications are now closed. Very unsure what to do from here, any help much appreciated.

I know you can automatically Sleep and Hibernate your computer with a timer. But these affect running programs and stop downloads ... so I was wondering if there is a way to automatically Lock your computer with a timer?

We are trying to develop a small application that can monitor the programs/processes that are executing in a windows machine.  If the program/process is not supposed to run, it should be blocked. It works similar to an antivirus.  This is the basic idea.  I want to know the ways to hook into the OS to get notified about every single program/process trying to run in the machine.

I'm afraid the answer is "it won't due to new security features", but I'll ask anyway.  I have a USB Flash Drive I run Portable Applications on (who doesn't, right?). I use PStart to start up a nice menu I've been using for a couple years, have my configuration dialed in to something that is productive, so I'm not inclined to just switch to another program.  I have an Autorun.inf in the root of the drive. Its contents:  [Autorun] Open=Applications\pstart\PStart.exe Action=Start PortableApps Icon=Applications\PortableAppsMenu\PortableAppsMenu.exe Label=PortableApps   When I insert the device on Windows 7, I get prompted to choose from a variety of autostart things I don't want to do:    It worked fine on XP and Vista, on inserting the PStart.exe would start up and I have menu.
