As well as being an amazing Monty Python song there's a bit more info on these people pretending to be Microsoft.
The company may also be using names Comantra or Supportonclick or Logmein123.

This YouTube video helps a lot, major respect for the chap here for leading them on and playing dumb.
Some people even report leaving them on hold for long periods while they go and do some washing up or laundry.
Another excellent tip is to put them on hold then have a friend take the phone call and pretend to be the local police, the scammers normally claim you called them !

If you listen to that Youtube audio very carefully you will realize that they don't know anything about your computer, they are asking for all the details and they are simply asking you to show event viewer messages.

Event viewer will have notifications and warnings, that's it's purpose - don't forget you can export the current view then clear all your logs, come back a few weeks later and see what's going on.
In normal use you will get messages in there, that's it's purpose and the scammers are simply playing on your fears and attempting to get money from you.

Another youtube link that has lots of "supportonclick" scam recordings is:

I have added Youtube videos on the right hand navigation bar so you can view the most useful ones anyway.
If you can't see the video list then you might need to check browser settings.
(Ubuntu users may need to check plugins - I have "mozplugger" and "mozilla-plugin-vlc" installed so the videos appear fine on my system).

As long as you remember not to install any software , let them link up or give them any personal details then have fun annoying them and wasting their time.

Don't forget, when your finished with them, tell them to fuck off !
