I recently purchased a used lap top with Windows 7 Home Premium on it. I wanted to change all the settings so that there in my name. I was able to make myself the administrator and was also able to put the PC in my name. Now i'm just trying to change the name of my documents folder. At the moment when I open a program is says C:/user/Michael...and my name isn't Michael. I went and right-clicked on my documents and clicked properties. I then had a window pop up where I was able to change the name, but when I tried to press ok a window popped up that says, "Error 0x80070057: The parameter is incorrect." So I am unable to fix the name. I tried changing my permissions but its still not working!
To make my life even worse I tried to contact someone at Microsoft and in order for this to be free for me I have to enter my identification code. I entered it and the website won't take it. Soooo I could REALLY use your help! Thanks to anyone that thinks they can help me out!
