With shareware, cheap does not equal low-quality and there are plenty of examples that prove shareware often outperforms the quality of commercial software time and time again. How much savings are we talking about? You could purchase a quality word processor, spreadsheet, database program, or system utility anywhere from a mere $15 to under a hundred. Basically, computer errors are the result of a number of things that may or may not have anything to do with the way the computer is used. They "operate" whenever there's a conflict among commands. Remember that computers essentially run off of a series of commands and it's usually a smooth process. When you think about upgrading your computer to a new operating system, be careful to make sure that you have the necessary hardware components. We tried to upgrade one of our Windows 98 machines to Windows XP, but we were cautioned that the former may not be hardware compatible with XP technology. Apparently, the Windows XP operating system requires components that weren't developed at the time Windows 98 was distributed and if we were to install Windows XP on this machine anyway, the new operating system would look for hardware that the computer didn't have. We tried to convince him that a fully functional computer is one that is personalized with specially selected hardware and software accessories - and that the computer purchased at the store doesn't come with these things. Unfortunately, all of our convincing was to our avail. Our client insisted that he should never need more than what came with his boxed product and that we were just trying "bilk" more money out of him. On the other hand, it can also grant the same access to those who aren't supposed to get it. Although it's a rare occurrence, hacking has become the biggest criminal nuisance in computer history. Make no bones about it. There's nothing innocent or cute about the hacker. Today's hackers aren't the pimply-faced teen rebels that you might be thinking of. For the life of us, we can't figure out why anyone other than a rocket scientist would want to install a different version than this free one that comes pre-installed. Windows calculator has two interfaces: an easy one, and a scientific one. So perhaps a rocket scientist could fare well with Windows Calculator after all!
