    What do you mean by "shared login password"? ...

    a. Everybody uses the same account? If so, changing the password would, of course, affect everybody using the account.

    b. People have different accounts but all use the same password? If so, of course changing the password for your account would not affect the other accounts. However, it would complicate how you can share your files with others.

    c. You mean something other than (a) or (b)?

    We are all on a shared network so the login credentials for logging onto the computer itself are the same for everyone. I tried changing it from the login screen and it changed all the computers passwords so I want to make only my computers login password different so no one can use my computer when I am not at work

    This is something that you need to address with your boss. Whether or not it's possible we cannot assist with a request like this without knowing if you're authorized to make such modifications.

    This is also a larger issue which you need to bring up to your management. Having shared passwords is never a good thing in a corporate environment. You have experienced one of those reasons but based on what I'm seeing, having a separate login wouldn't have prevented that incident from happening. Why I say this is because most likely everyone would probably have admin privileges which means anyone logging on to a particular PC will have all the rights do anything they want on it.

    The use of unique log ins also provides accountability through auditing. If someone screwed something up and did so without authorization, then unique log ins would allow auditing/forensics.

    It appears there needs to be an entire overhaul of how your IT systems are implemented.

    We are a small office with no IT system. My boss doesn’t care if I have my own log on password to keep my computer free from other users. He just doesn’t know how I can achieve this without affecting everyone else’s shared log in password. I am in school for computer security and I would like to figure this out as I’m learning all of this anyways. If you have a solution to share, I have permission to do so. I want to make my computer so as if you were to turn it on then the next log on shared password which is the same for all computers is what I want to change. I tried changing it and it changed everyone’s password I talked to my boss and he thought I’d be able to change only mine and wasn’t sure how to do this. As stated we don’t have an IT department if we have network issues we call in a professional company but otherwise if I can figure it out he is more than ok with obtaining this task as my computer was recently destroyed by someone allowing their child to play on my computer while my boss and I were on vacation and they installed a software virus which corrupted my computer beyond repairable. Thank you.

    Doing this gets real involved. It's not appropriate to walk anyone through this on an online forum. There are people that do this for a living which tells you it's not something simple that can just be done in one or two forum responses.

    As far as your boss not caring, he better. Because it opens him up to all sorts of liability. If someone were to surf kiddie porn on one of his computers, not only will the person (if you can figure it out with no auditing and accountability systems in place) be arrested, you can bet your boss will have to deal with the police on this matter too. I don't know what business you all are in but there can also be blow back from any customers you work with on proper security of any data between your company and them. This is a total disaster waiting to happen and I wouldn't want to work for a company that conducts business this way. Because who knows how he is protecting your personal data as an employee.

    If you're so inclined, you can copy and paste this reply to send to him so he gets the idea why it's important to take this seriously. Also, this is not a learning project for anyone trying to do this for the first time with no knowledge. The company is best served by hiring a consulting firm to come in and set up a proper IT infrastructure.

    By sharing the same login credentials, Windows 10 has a default setting to Sync across all computers using the same credentials. And the malware could migrate to all systems, infecting them as well.

    So, you have to re-install Windows 10 on all those 10 computers. First backup all data on all of them. Buy 15+ USB memory sticks. ( 128 GB capacity aproximately $16 each ) So each person will have to do that. Give them an hour. Then download the MS Media Creation Tool on a clean computer ( not one of those 10 machines) Run it to Generate a Windows setup USB memory stick. Generate several USB memory sticks so you can do the Windows re-install on several machines at the same time. Then boot the USB memory stick on each computer, skip entering the Windows product key, as MS can determine if the computer had Win 10 before. Do Setup > Custom. Delete all partitions ( because you don't know where the malware placed its hidden files. Antivirus programs miss out things to quarrantine all the time. ) And let setup use the unallocated space. That takes half an hour. When you have several USB memory sticks to run Setup in parallel, you can reinstall, lets says 5 computers, at the same time. At the 3rd reboot, setup will ask for user account name. Let each employee choose his own account name and password.

    Then you setup the network access so that each employee can reach the shared network drive. Then re-install the programs that each person needs.

    Could be all done in one afternoon. Not a huge undertaking. The variable is the installation of mission critical applications - I don't know how complicated it is to do it.
