Bro,I have a serious problem with windows 7 which is very annoying, when opening
a folder is always open in new window ... but the general settings in 'folder
options' control panel is set up on the 'Open each folder in the same window'.
it happened after I downloaded Internet Explorer 9 using windows update in
control panel. :confused:

Please give me a solution and thanks in advance.

I think a virus in your computer install best antivirus like Kaspersky or avira

:thanks: a lot for ur clue bro.
