Things went well mostly until it’s failed, with an error code 0xC004C003. He took out the wallet and paid right there in the Activation window to upgrade his Windows 10 to Pro edition. Luckily, that didn’t stop him from using it. But his Windows 10 is only a Home edition that doesn’t have the business features such as BitLocker. A friend of mine wants to protect the data on his computer so I suggest using BitLocker to encrypt the whole hard drive.
