Today I worked on a friends computer to get their wifi working. It was a pleasure for me to help some good people out. They have Windows Xp and a Linksys router.
Windows as a operating system is a magnet for malware and download schemes that install unnecessary software on ones computer. Most Windows computers are shipped with bloatware and it just slows the system down. Then you need software to clean it out and antivirus software to keep it safe from the hackers who seek to do mischief on your machines.
Windows XP is a dated operating system that many people still run because they cannot afford to upgrade or their hardware is not able to take Vista, 7 or the upcoming release of 8. No wonder so many folks are migrating to iOS and Apple products.
Viruses continue to plague much of what Windows does. I am glad there are utilities to help clean things up and keep things running as smooth as possible. I just hope that computing overall becomes cheaper and more efficient for the users out there who are still using dated operating systems and machines. This is the reason why I use Ubuntu because its free and I can do what I need to do on my machine.
