Autorun.inf on brand new USB memory sticks

As far as I can remember, MS released a security update that was supposed to prevent autorun.inf from starting executables on memory sticks.

The last two brand new memory sticks I bought this fall tried to install software anyhow.

Maybe I could press some key while inserting the stick.

Anyway I don’t like it, and there was no info on the package.

Share your thougts.
