I just want to verify I'll still be able to use Google Voice on my desktop or laptop running 8.1 as long as they are not a Windows phone.

Google just can’t seem to make friends with Windows Phone. The latest crackdown will come in May 2014 when the search giant begins to enforce its terms-of-service for its Google Voice service, barring third-party companies from making apps.

“Finally, we want to make Google Voice as secure as possible. There are a few third-party applications that provide calling and SMS services by making unauthorized use of Google Voice. These apps violate our Terms of Service and pose a threat to your security, so we’re notifying these app developers that they must stop making unauthorized use of Google Voice to run their services and transition users by May 15, 2014.”
