If you have had problems in the form of a crash or some similar in Vista like me, you have without doubt also been seeing that Window tries the fix problem for you. This requires however that you approve that one error report to be sent to Microsoft, what you self-evidently should do.

After an occurred error, windows almost all the time pop up a page with links to more information. Often you may get a very exact description of how the error can be solved or to be avoided. This is I love by vista. It helps a lot actually.

You can also afterwards look on those problems and solutions that have been occurred earlier by others. Just type only "problems" in search bar during the starter and then open "problem reports and - solutions".

You can afterwards look under "Show problem history" on the left. You can also choose "look for new solutions" in order to check is there is some new solutions to old problems.
I
think this shows how forward Microsoft has come with their operating system. You can fix almost all the problems by yourself. But for big problems like viruses and spyware and dll errors, the only and the best way is to use tools like antispyware, registry cleaner and other security softwares.
