Microsoft support is good if you pay for it.
So I'll opt, as in years past, to pass.
If you are a cheapskate, like me, you can get free support sometimes if you subscribe to the MS newsgroups. They have one for pretty much every product and version, and the Microsoft MVPs answer a lot of support questions there, free of charge.
No guarantee, and you may have to wait a few days for someone to reply, but worth a shot if you refuse to pay MS for tech support.
