If you happen to be sharing a computer with other users, it’s very reasonable to be concerned about your privacy, and whilst it might be ideal for everyone to have their own PC, this is not always an option. If you can’t access a private computer, there are several options which should allow you to keep your computer activities secure.
The first step to creating a more private computer is to create user accounts for yourself and anyone else using the computer. These accounts can be password protected for each user, or you can even choose to leave certain accounts open for guests or other users.
To create user accounts in Windows 7, you will need to open the Control panel, and in the User Accounts and Family Safety section, you will be able to select “Add or remove user accounts”. This will take you to a screen where you will be able to select the “Create a new account” option; from there you will only need to choose an account name and select the type of account based on the privacy you want. If you are the main user or owner of the computer, you may want to make your account an administrator account to allow yourself access to other accounts and control the changes made on your computer. By pressing Ctrl+Alt+Delete, you can select the “Change a Password” setting and adjust it as you wish.
If you have very private documents or files on your computer that you are worried other users will try to access, it might also be a good idea to install free encryption software such as Truecrypt to set up a secure vault.
