Games for Windows Live & Xbox Live help needed

When I got my Xbox 360 in 01/2011, it wouldn't let me use my hotmail email account to create my Xbox Live account. Therefore I used my Gmail account to do so. Over the last 2 months I've gotten 4 pc games, 2 ehich needed a Games For Windows Account. That account let me use my hotmail account info. I realize Game For Windows is actually under Xbox Live now. In February my current Xbox 360's Xbox Live expire's in February. Does anyone on the forums know how I change that account to match my pc's GFWL/Xbox Live Account, so both account's are the same. I plan on renewing in February and amm ordering a new Xbox Live 12 month card Tuesday from Newegg.

Not sure but maybe THIS?

I forgot to mark this as solved. I later found the answer on Xbox Live. I'll find out next month if it work's, as that's when my current Xbox Live Gold run's out. I'm gonna let the Xbox Live account lapse and then use my Games For Windows Live details, as they're now both the same on the web. When I got the Xbox 360 last year when the 2 were seperate from one another, it wouldn't let you use the same account/email address which is stupid. I have to have the G FW account as 2 of my pc games need it. I only use the Xbox for streaming internet video, etc.
