When you boot up you are greeted with a login screen and the name of your account. It is that name which may or may not have spaces in it. If you still don't know what I am talking about, if you bring up a command prompt (it it is not still open from before enter cmd in the search bar followed by the enter key. Then type the following followed by the enter key:
echo %USERPROFILE%
You will see something like:
C:\Users\some-directory-name
The question is whether that some-directory-name has one or more spaces in it, such as:
C:\Users\John Doe
