DO NOT INSTALL the sP1 for Vista it srews up everything - browsers, email it was a mess. I took it off and now everything is back to normal on my Vista machine.
I’ve been on Vista and SP1 for months now and have no complaints. I am a software engineer by trade and heavy end user ( sorry no gaming BS ) so I cannot quite get the beef. Vista works fine once you turn off the unnecessary overhead junk and learn how to use it.
