windows stability

In the past few weeks I have spent a lot of time repairing windows (xp and me) systems. The three systems I have worked with are all run by people who practice 'safe' computing and do periodic maintenance. Even so, they have had viruses, corrupted system files, missing system files, and performance and stability problems.

I hack around with my Linux system quite a bit, yet I never have had the level or frequency of problems that my friends, who use Windows, seem to have.

It seems to me that the fundemental problems are that Windows' architecture is not too good and that windows has become too big and complex for Microsoft to effectively manage and maintain.
