There is no WWW in microsoft support. It is
http://support.microsoft.com... Also, the odds of someone from microsoft spending 30 minutes fixing your computer are just... astronomically low. I can't see it happening. It's not even part of their policy...
If you bought a prebuilt machine from DELL or HP, then DELL or HP is your tech support. If you built the PC yourself, YOU are tech support. Other than activating a windows license that is giving you a hard time, Microsoft ain't gonna do jack squat for you. Especially not for half an hour.
I'd hate to see what information you've had stolen or what spy crap you've had put on your PC by these "microsoft support" people. I'm not even going to click on that link but I'm 99.999% sure you got screwed.
I'd suggest at this point that you do a full reinstall of your Windows 7 and just do the windows 7 rollup patch manually and be done with it. Your machine is almost definitely compromised.
