Which version of the Kernel Ex is safe to download as there are lots of links on the above page and it is not altogether clear. I am running an original 12-year old Intel Pentium III desktop, 866 Mhz processor, 256 MB RAM, all official Windows 2000 security updates installed until support ended in June 2010, plus the new update from this month (KB2722913) after reading about that. I also use Office 2000 and Outlook Express on this PC. I have newer laptops running Windows XP and Windows 7 but there is one good reason why I still use the old Win 2k machine a lot: because for many months my wifi adaptor can pick up a strong unencrypted wifi signal from a neighbouring property when used on the Win 2k PC, even though the signal is invisible when you scan for it (it connects automatically when I switch on my PC). However, despite many attempts, I cannot detect nor connect to this same free wifi signal using the same adaptor in exactly the same location on either of my laptops. Therefore my old Win 2k PC is saving me a lot of money each month in broadband fees which I would otherwise have to start paying again. For this reason, I would like to keep using it for as long as possible. I can only presume that the reason I can connect to this wifi on my old PC whereas on my other computers I can't must be something to do with the Windows 2000 operating system itself. I would also like to see any relevant instructions on how to download Kernel Ex, or is it just a case of downloading it and then running it? Which folder do you put it in and do you have to remove any other installed security updates first?
