I'm on Windows XP. Every time I try to make a change from msconfig, I get an error message "An Access Denied error was returned while attempting to change a service. You may need to log on using an Administrator account to make the specified changes". However, I'm then asked to reboot my system, and generally the changes get done, barring NvCpl which I can't disable from start-up using msconfig. I am the only user and Administrator on my computer. I was suggested Ratscheddar but it's presently not available, after Castlecops closed doors. Also, when I open up "My Computer", it shows a 3 1/2 Floppy [A:] drive, which really should not be there because I do not have a floppy drive on my computer. How can I get rid of it? It'd be great if someone could help me out. Thanks a lot.
