Yes, exactly Kyle... so there is no chance we can say something is more secure than something else... maybe at this particular point, but very soon, as soon as those hacker find it interesting to "play with", they will attack even those which we think today, are most secure OSes... that's their food, and I believe it will always be like that... Regarding those upgrades to new OS, I really never ever had a single problem... not a glitch. I even do remote updates to my father's PC, and you all know he is in Croatia, and I'm here in Canada. I never ever experienced anything weird or something. It's just, you have to be carefull and know what are you doing... and most important read those notes Microsoft gives you to read before any update... read what is it for and do you really need it or not... sometimes you have a bunch of really unnecessary updates, so no point of updating your system... for example: Bunch of language updtes for more than 30 languages for Windows 98. Why would I have to update my father's PC with some Korean language updates or something third... but some people never ever read, and they just automatically download and install all kind of crap... and after that, they wonder what happened with their systems... they are sooo slow, they don't respond etc... sometimes you will even see a note from Microsoft: "...if you previously updated your system with that, do not perform this update..." etc. People just have to read more... every single OS is awfully complex thing, and we have to take it into consideration whenever we want/need to change something.
Cheers !
