Windows 7: The Application Was Unable To Start Correctly, (0xc0000022)

Every time I try to log in to my user, (which is administrator) I am met by a box containing the error in the title. I am able to use safe mode fine (which I'm using now) and have tried doing numerous scans and fixes such as SFC-Scannow, Norton Antivirus and System Restore but each one cannot find any threats. Close to the time this started happening, I turned off my laptop by the power switch instead of using the "Start" menu as it was taking ages to switch off. I am pretty sure this is the reason that this is occurring so please could you help me and give me a solution if there is one.
Many thanks.

If it doesn't work out, please post back for further suggestions.

Thanks for your reply. I had already tried this method prior to posting this thread, but had no success. I have however, learnt that werconcpl.dll is causing the problem, as after receiving the first error message and being taken to the black screen, I am prompted with a message stating "There was a problem starting werconcpl.dll, access is denied." On safe mode, the file is present in System32 but in normal mode task manager, it is not. Please if you know how to fix this could you suggest some methods to fix this?

Thank you,
Luke.
