I have a Acer Aspire One that crashed and blew smoke out the power plug hole a few weeks ago. I had Windows 7 installed on it. Sent it to the factory. They replaced the motherboard, keyboard, LCD cable and HARD DRIVE........ S'ok didn't loose any data. Knew I'd just re-install all of the programs I had before. When I turned it on, found that they had installed VISTA with an "User owner" of ACER. After reading found out that it was better to upgrade to Windows 7 than do a clean install, so that's what I did. Works good, except it still has an "user owner" (don't know what else to call it) of ACER. I'm the administrator, but when I install some software it says it's registered to ACER. Is there someway to change that over to me or do I have to do a clean install?
