Once upon a time, the Microsoft has developed two separate operating system families for consumers and businesses respectively. We are referring, of course, to Windows 95, 98, and Me on one hand and on Windows NT and 2000 on the other. The versions of the operating system that were addressed to consumers included just one type of user account, the administrator. This means that all Windows users have unlimited access to their features and data, which unfortunately also applies to any malware programs that were unknowingly running.
Instead, business versions included restricted accounts, which offered more flexibility as it ensured that only the administrator can install programs, hardware, and perform other important settings and tasks. Windows XP borrowed the philosophy of NT and 2000, allowing the creation of accounts with reduced rights. Unfortunately, the original user account was administrator type and so most of us do not take advantage of the extra security offered by the operating system.
Post Windows Vista, Microsoft went one step further by incorporating the so-called userAccountControl (UAC). This feature requires the user to approve a series of actions, such as installing programs, delete files κ.λπ. Αν ο χρήστη έχει κάνει log-in as administrator, then, in the box that appears, you just have to press the Allow button. However, if he is not an administrator, then he should also type the Password of the administrator to continue.
UAC can become quite annoying, so we can disable it, after first considering the consequences it can have for the security of our computer. Go to the control panel and the User Accounts section. Click Change Settings and a new window appears which includes a large slider. If we pull it all the way down, the UAC will be turned off completely, we will not be notified of anything and our computer will simply become… an open vineyard.
