Ever wanted to be one of the lucky beta testers for none other than Microsoft? Welp, now’s your chance…

Just incase you didn’t know how it all works, in order to become a member of a beta program at Microsoft, you typically log in with a Passport account at Microsoft Beta (formerly Betaplace). You then find the link indicating that you were provided with a Microsoft Guest ID. After entering the ID (which we’ll get to in a minute), you’re taken to the project’s intro page. Remember to complete any “Invitation” or “Nomination” surveys displayed, otherwise you stand no chance of being accepted!

After the survey responses are reviewed, you may or may not be accepted, based on the answers you provided. They generally look for a wide variety of testers, so you never really know.

So what is this magic Guest ID you have to enter? Well, it’s a random mashing of the Beta program’s name. Sometimes you’ll come across a story at WinBeta or BetaNews that lists the ID when referencing a program, but generally you’ll be sent an invitation directly from Microsoft referencing it.

Thanks to the power of the internet, that is no longer true! There’s a long list of active Beta Guest IDs here!

NOTE: This is in no way a guarantee that you will be accepted to the program. I’m also not able to confirm 100% accuracy of this list. I have glanced over it, and from the half dozen programs I’m a member of or have been invited to / applied for, it appears valid. YMMV (Your Mileage May Vary).
