I have a Dell Inspiron 2330 all in one out of warranty. Originally came with Windows 8 and have since updated to Windows 10. Well it would not post and had to replace motherboard and reinstall Windows 10. Of course Windows will not activate since it is a new motherboard. The PC also did not come with an OEM sticker for Windows and the key is unrecoverable as the old motherboard would not post. I called up and said there was nothing Dell could do and a new purchase (over 100 dollars) of Windows 10 was needed. Am I not even given the choice to go back to Windows 8 with license key for 8? This is unfair. Your motherboard went bad and believe I should be given at the very least a license key for Windows 8, the possibly by supplying that to Microsoft they would honor my upgrade back to Windows 10. Bad business Dell if this is true!
