So far I have tried many possibilties, Checksur, sfc,WindowsUpdateAgent and nothing solved it. In my CBS.log, I've plenty of ERROR_SXS_COMPONENT_STORE_CORRUPT (OpenCanonicalDataKey) errors and in my registry HKLM\COMPONENTS is shown but it was empty until I try and add the base key (CanonicalData,DerivedData) but still, alot, like couple of hundreds I guess, keys are missing. Now I wonder how to rebuild COMPONENTS hive, I believe it isn't as simple as copy-pasting it from another computer. Any idea? Thanks in advance.
