Its not new for Microsoft to release a large number of updates for their products.
Lets face it, no company creating software is going to produce something bug free .

Microsoft create or own so many applications( far more than apple or oracle )that these updates look large but are updating several core programs, such as

Office

Windows Media player (which in some part is also built into windows)

Run antivirus of some kind. The best free one is AVG free edition.
If you are a student check if your university gives you a free antivirus application
