Can anybody help me solve 0x8004fe21 error

Hi Genuine windows error keeps popping up and I can't figure how to solve. Copy of diagnostics below. Any step by step help would be greatly appreciated, as Microsoft's solution is to buy another activation code it seems! Code: --------- Diagnostic Report (1.9.0027.0): -----------------------------------------
