I had a Dell engineer arrive this week to replace the hard drive and screen on my Dell 7537 laptop. Dell customer support downloaded windows onto my usb key so that it would be ready for the installation.
Everything went fine and he installed windows on my laptop, but we didn't connect to wifi as I said I would use a faster internet connection later to download the drivers.
Now it turns out that the windows key used by the dell engineer wasn't the correct one and I can't activate my version of windows. Error code 0xC004C003. Is this because I originally had windows 8 on my laptop and then took the free upgrade to windows 10? I have asked if dell support could provide me with a key repeatedly but they keep deflecting the question.
Any help would be greatly appreciated
If Windows 10 was on the system prior and activated, you do not need a key, it is kept online. Just being online with a private network account should allow the system to activate.
A hard drive replacement will not trigger an activation problem and I don't think a screen would either, so it should work.
It does matter if you had Win 10 Home or Pro for the prior install.
Can you install RWEverything and select Access ACPI tables. Do you have a MSDM table?
