Windows tell me it's not genuine

I have a Sony Vaio laptop, with Windows 7 pre-installed. I switched to an SSD, and cloned the old drive onto the SSD. Ever since, Windows has told me it's not genuine. Here's the MGADiag output: Code: --------- Diagnostic Report (1.9.0027.0): ----------------------------------------- Windows Validation Data--> Validation Code: 0x8004FE21
