Once you change your computer's name is there a log somewhere with the old name?

Question

I recently made the mistake of changing my computer's name in the Control Panel. And now I have to change it back but the problem is, I dont know what it was, because it was a lot of numbers. Is there any log that would keep this kind of information somewhere on the PC?

Answer 1

If you have not made many changes it may be in your registry. Try running start-run-regedit and look for the following keys (line up to AciveComputerName is one line)
HKEY_LOCAL_MACHINE\
SYSTEM\
ControlSet003\
Control\
ComputerName\
ActiveComputerName
You may have up to 3 old copies (001, 002 and 003) If you have made a lot of system changes, they will all have the newer name
Be aware though, unless you are using file sharing on your machine, or are part of a domain or active directory it should not make a difference if you change the name.
