I am using Vista Home Premium. It did work alright at first. Then after a long use, a problem occurred. I don't know why. Did it occurred accidentally or because I set up some programs? The problem is that Windows doesn't remember my setting and option I choose. For example, in Firefox, I choose it to open the previous site, but it opens up in blank. And, in Free Download Manager, it doesn't save to the last path I save, as it previously did. Some programs keep asking the same thing while they should be occurred only once. And, more.
What should I do to fix that problem? Or, any program to solve it? Or, I have to reinstall the Windows?
Thanks in advance for any reply.
