As a home computer user, your most crucial task is to make sure your data is backed up, and that you’re backing it up regularly.
The 2nd most important thing? Create and use a standard user account. By default, Windows (XP, Vista and now 7) create administrative accounts as part of the initial setup. These accounts are necessary if you need to install software, change security settings, etc, but for everyday use they are a liability.
Why Not Always Be Logged in as an Administrative Account?
In a word, protection. When logged on with a non-administrative account, viruses and spyware can’t infect your computer as easily as when you’re logged in with an administrative account.
How to Create a Standard User Account
Each flavor of Windows has its specific way for creating a standard user account, but the process is similar:
Windows XP
Windows Vista
Windows 7 (Ironically, this nicely-written how-to guide is from UnixWiz.net)
Whether you’re using Windows XP, Vista, or 7, it’s very easy to create and use a standard user account for your everyday tasks. Doing so makes your computer much less vulnerable to virus and spyware infections. It’s much more time-consuming to clean up an infected computer than to prevent an infection in the first place, so make sure you are using a standard user account for your day-to-day tasks.
