Hi,
I have a Dell i5 N4050 laptop that came with pre-installed Windows 7 Pro. Couple of weeks ago, the laptop freezes at starting windows screen. I didn't created a recovery disk or restore point to bring back the laptop to its good condition but what I did was reinstall the Windows 7 Pro instead. When I provided the product key an error in activation occurred " product key doesn't match current windows SKU"
I got some help from Microsoft Technical Support and was asked to provide the Windows 7 Pro product key. They found out the product key is blocked by the OEM. I was advised to contact the OEM to resolve the issue of Windows 7 failed to activate due product key doesn't mathc current Windows SKU.
