My computer has the operating software on drive C and data on drive D.
Somehow I have created (or Microsoft has created on my behalf) a folder on drive D called 9c5819f8ea90f2a681b357a90a. It must have been Microsoft as I could not dream up a folder name like that. I find that it contains Microsoft update ND40-KB2840628.
The update appers on my update history as successfuly installed in July 2013, and I have been attempting to delete the folder and its contents from drive D.
I tried deleting with administrator priveledge by following the instructions in 'How to enable and disable Administrator account through the Computer Management Console' on this site, but have not been sucessful. I rarely use Administrator access and maybe did not got that right.?
Attempting deletion without Administrator access brings up a dialog box stating 'I need permission from SYSTEM for that action'.
I would appreciate any advice on how to proceed to clean out this unwanted folder.
