It sounds good to call your computer by a nickname, and it's much more fun to give it an official name. Your machine must have appeared on your home or office network with an unusual name (such as LAPTOP-AE12A1). Your user account is different from the name of your computer or device. Have you recently attempted to change the name of your computer and received an error stating that the name is invalid? Don't worry, we went through something similar and came up with solutions as well.
