I have installed tcpip simultaneous patch "VistaTcpipUacPatch2.2" but everytime I need to press F8 button while booting for my wireless connection to work otherwise its not connecting to internet. I have uninstalled the patch but even after that its the same. I need to press F8 everytime even after uninstalling the patch. Is there any way so that my system can be reverted to normalcy. And also my laptop has 2 headphone jacks but after this patch one of them stopped working. I dont have the Vista CD. Kindly help.
