hello
i'm glad i'm waiting to update to Win 8.1 for the time being as i see alot of people have trouble with it
it's not the first time and will not be the last from Microsoft i'v seen it with Win XP sp2 and i'm sure
other SP's also
thay can not guess issues with every combo of software and hardware out there on peoples computers but most forums
i read have someone in trouble in one way or the other and some people could have trouble and not know because the
trouble is something thay do not use often enough to know yet

just to name a few places
i know there will always be someone with trouble with this type of upgrade but i'm glad to wait and let Microsoft sort
it out before i jump in so i will just set back and watch for a bit
