Brink:
I am using registry editor from command prompt. Drilled down to c:windows\system32\config inside the Load Hive dialog window. Have selected (checked box) the SAM file; clicking on Open opens error message that says:


SAM
This file is in use.
Enter a new name or close the file that's open in another program.

I am at a loss, since I am not running any other program!

Any suggestions?

Problem with BITS service - Lockscreen

It begins with my Lockscreen not changing pictures when Spotlight is selected,. It works in preview, and Windows+L, but not when the system is shut down and restarted. I ran the background troubleshooter and received a message, "Problem with the BITS service.
The requested service has already been started. More help is available by typing NET HELPMSG 2182." The listings under that search do not relate, they all concern windows update. I have run sfc /scannow. All is well.
