This is probably caused by your antivirus program.
Windows Mail is incompatible with most McAfee and Norton
antivirus programs. If you are using either of those two, it is
best to uninstall it and replace it with a more compatible
antivirus, such as the free version of Avast: http://www.avast.com/eng/download-avast-home.html
I don't follow you.
Re "that's what i did". Which action, I mentioned two different actions.
Re "window mail made more problems..i needed to unistall it". Which,
Windows Mail or Windows Live Mail?
If you don't like either mail program, you may want to give
Mozilla Thunderbird a try.
