I purchased a Windows 11 Professional upgrade - Don't do it.
I purchased a Windows 11 Professional upgrade key from PC World and received a product that could not be activated. Microsoft rejected the key with error 0xC004C008, which means the key had already been used on another device. When I contacted support, they sent me a second key — but it was a Windows 11 Home key, not a Professional key. Windows immediately identified it as the wrong edition.
Despite multiple attempts to resolve the issue, PC World did not provide a valid, unused Windows 11 Pro upgrade key and repeatedly gave incorrect information about the keys they issued. This was a misrepresented product and a very poor support experience. I cannot recommend purchasing software licenses from this company. Finally ended up getting my money back thru a charge back.
