COMPONENTS, (found in HKEY_LOCAL_MACHINE), was exported by me onto the desktop as it had been a step on a microsoft help guide that I had been following...

Thing is, i'm not sure whether its vital I should get it back to its place. I disable User Account Control and try double clicking on it/ loading the Hive in the registry, but error is denied every time. What should I do?
