Windows 7 Installed windows, tells me I need to enter W7 pro key, I have home premium

So yeah, I re-installed windows after getting my new hard drive and it tells me i need to enter a W7 professional key when I only have a home premium. How can i resolve this? Thanks!

If you have an OEM, there may be a problem.

The fastest and most secure way to solve it is to contact Microsoft, have all Product numbers and Keys available. Plus, if your computer runs, have it running.

which exact version do you need? Pro or Home Premium?

I repeat myself, the real way is to check with Microsoft, or with your retailer. About keys, we've had a discussion, and kemical's view is worthy to note: http://windowsforum.com/threads/buying-microsoft-keys-online.191161/

Not insinuating anything about Billy Bell's post, but do not "buy a key". The key is free of charge, available to any legitimate Windows OS - they do understand difficulties with installation.

Proper conduct provides proper result.
