Note that you have not bought anything from Microsoft: you are a Dell customer. If not, you can go to Start and type slui.exe into the search box. If so, there should be a link that says 'Activate Windows Now' in System Properties. It seems it's being seen as a new installation. Microsoft gives you 30 days to activate your copy of Windows 7, with increasingly frequent prompts, which is why it has become a real problem now. Only if that fails will you have to describe the problem to a human being. Follow the instructions on Microsoft's website: Activate Windows 7 on this computer. When online activation fails, you should be given the option to choose a phone number to go through an automated activation process.

You should also be able to use the COA SLP key to activate Windows 7, but this will probably involve a phone call to Microsoft. This is the key on the Certificate of Authenticity (COA) sticker that should be on the back of your laptop, or possibly hidden inside the battery compartment. Your Dell should also have a second (different) Windows key, known as the COA SLP. If your created recovery media or backed up the hidden partition, you could try using those.

Certainly, the built-in SLP key should work if you re-install Windows from Dell's recovery partition. This key is usually locked to the BIOS chip on the motherboard, so it should automatically reactivate Windows even if you change the hard drive and other parts. In these cases, Windows is pre-activated in the factory using an OEM SLP (Original Equipment Manufacturer System Locked Pre-installation) key.
