Definitely brings back memories of the Windows glory days, even if I was never completely around to experience them in their prime. This commercial kinda feels like a time capsule. It's nothing remarkable to the average viewer but it's kind of nice how the company went out of their way to cater to the otaku market with this character. Wish I was able to still buy her software set, but I'm far past Windows 7. It's hard to write a lengthy review about something so simple, and something so relatively obscure that it's seldomly mentioned on the world wide web. However, there's no doubt that you(whoever randomly stumbles upon this) will feel similarly to me in a way.
On the topic of the character herself, the art style is adorable as well as the character design. She's become a personal favorite "OS-tan" of mine due to the sheer amount of cute official art that comes jam-packed in her software and commercials.
