Are you having a lot of trouble with it? If so, it might make sense to just reinstall 7

Who did you buy it from?

Acer Support website shows that model available since XP, so it likely had prior OS but if store installed 7 it probably mass installed it without in-place Upgrade.

Does it have a lot of bloatware? Most tech enthusiasts won't even bother trying to uninstall unwanted bloatware as it creates even more OS corruption, just proceed directly to clean install.

You'll need the WIndows 7 DVD, though. Did your seller supply one?
