What good is produced by Microsoft? Windows really is not the best operating system. Just due to the fact that bill gates had the advantage due to the fact that he was now cornered the market and will not allow to competitors.
Windows may not be the best operating system, but their support service is the best. Also, the other operating systems (especially Linux) is not compatible with most of the software and PC games. What is the use in having a computer, if you are unable to use any software? Also, I can't blame Windows for this. There are thousands of Linux versions, and software which is compatible in one version may not be compatible in another.
