I would like to say this is a good effort, but it really seems as if you haven't made an effort at all.
The initial problem I have with this submissions is that Windows ME hasn't been relevant in well over a decade, and we've had two disastrous Windows Operating Systems since then (Vista and 8) that you could have made fun of, but you went with a severely outdated joke about an OS that a decent chunk of people won't even remember. ME was, after all, over a decade ago.
The best advice I can give to this is that you need to spend some time on writing something compelling, or consistently funny, or at least with a nice punchline, and then put the effort into doing it well. I get that you're probably new to Flash, or whatever program was used to make this, but that's only an indication that you, like so many other new animators here, need to spend time learning and practising.
The jokes were half-arsed, the additions poorly edited in, the lifted commercial was extremely low quality, and there was no momentum. As a premise, I feel like this had a lot of potential, but it was squandered on a lack of effort, and, unfortunately, although I feel horrible for doing this, I can't see merit worth even half a star.
