XP Home OS; When trying to update to SP3, I get a prompt to insert an XP Professional disc. I bought XP home, and it will not let me continue the update. So I ignored it for the past 4 months (constant security update prompts ignored) and as of today, all security certificate required sites will not work -I'm screwed. I'm tired of MS selling me stuff that simply does not work! No wonder this country is gone down the tubes. Guys like this are at the helm. And now I try to get help, and all I get to is that it will cost $59.95 to get a response from their tech department. The same department that obviously didn’t get it right the first time... I'm frustrated beyond all belief. No wonder Apple has gained so much ground. I'm about to take my 4 month old machine here and drive over it with my forklift; then go buy an Imac... (I’d drive over it with my car in the driveway, but would likely hurt the car)If anyone could provide an idea of what is wrong, I'd be grateful - Thanks1 person needs an answerI do too
