Hi Noel,
I ran the CHKDSK in elevated command as advised and left it running through the night. There was no report generated. On rebooting the earlier problem seems to have resurfaced and windows activation error 0x80070426 is appearing.
I again ran the earler commands you had advised in elevated command window to manually start the service and following is the report generated -

I went to services.msc and tried restarting the software licencing. It is set on Automatic but fails to start.
I was not sure if I should try to run the SFC or not at this stage.
Would appreciate your advice.
