Hi, I have C:\Users\NameThatIwantToRename I tried in Vista , right click : there is no rename option so I was opting to force it under Dos but that`s the result: "The process cannot access the file because it is being used by another process" I changed the username but the folder`s name did not change Someone told me that if I changed the name I will have troubles. the best way is to create a new user and copy/move all stuff in it. Is this true? Opinions? Thanks
