Broadband :: Windows Vista Online Slowing?

I have updated drivers or roll them back. Under computer, I right clicked on computer, then it shows like of hardware. Then I looked at date on driver and tried to update past june 27, 2006 or to roll many back . This increased my online speed but I could not get all drivers past that 2006 date & year, my computer thinks its the most updated version. It is not. This inability to change them or update still causes windows vista to be slower while operating. I guess I could buy the fix offered on web but I feel I shouldn't have to when I know the problem that microsolft built in. To bad microsoft isn't forth coming with an answer.
