I am planning to upgrade to Windows Me from Win 98 SE. I have heard that is worth it since you can back up to a pervious reg settings. My concern is this: I used the upgrade version of Win 98 SE from Win 95b, can I use the upgrade version of Win Me or do I need to use the full version? Can anyone give me any other pros or cons about doing this $49.00 upgrade since every other time I've done a Microsoft upgrade it takes me about a month to get everything else to work.
