Software that teacher can use to temporarily lock classes PC's ?

Here is another vote for NetOp. We use both NetOp and SynchronEyes, and NetOp wins by a small margin. Where SynchronEyes fails is it doesn't run as a service, only as a user level process. So you can't administrate the machines unless they're logged in.

Using NetSupport here

iTalc is obviously 'free' but comes with the added caveat of potential less support (I've yet to find a paid for support option for it), and it being not quite as polished as the commercial options (but then again, it is a lot younger).

 

ABTutor is the cheapest commercial option I've found and we use it in school. Very nice and reliable too in my experience - although keeping it up to date can sometimes be a pain.

 

The other options as others have said are NetSupport, Impero, Synchroneyes, etc... All of these cost a good amount more but then, each one has unique features and in some cases a significant amount of features that ABTutor doesn't have. However, we've never had a need for those features in our school.
