Hi Team, Apologies I believe I managed to fix my corruption. WW installed the below and a subsequent sfc \scannow didnt report any integrity issues. System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [May 2014] This tool is being offered because an inconsistency was found in the Windows servicing store which may prevent the successful installation of future updates, service packs, and software. This tool checks your computer for such inconsistencies and tries to resolve issues if found.
