Turn on Your PC’s Alerts

When you install software or update it, you are making a change to your computer. Operating systems have a way of warning users before they allow software to make changes.
•The User Account Control (UAC) window that pops up when installing something in Windows is one example. It was introduced in Windows Vista (if you are running something older – such as Windows XP, you won’t see this warning pop-up window).
•If you don’t see this warning when you install an application, you probably have UAC switched off, which is dangerous. It can be turned back on in the Windows Control Panel (Control Panel -> Action Center -> Change User Account Control Settings).
•On Mac and Linux comparable presentations can be made warning users before software is installed with administrative rights (usually a window requesting the admin password).
•Because software makes changes to users’ computers, and these changes may be good or may be bad, it is important that users know that they are installing safe software which will not harm their computers.
