To create symbolic link in windows 7,then easiest way is to use command mklink.
C:\Windows\system32>mklink Creates a symbolic link. MKLINK [[/D] | [/H] | [/J]] Link Target /D Creates a directory symbolic link. Default is a file symbolic link. /H Creates a hard link instead of a symbolic link. /J Creates a Directory Junction. Link specifies the new symbolic link name. Target specifies the path (relative or absolute) that the new link refers to.
Normally,we can use the option /D to create symbolic link.
Note:You need the admin privileges to run this command

Example:
To create a symbolic link named MyDocs from the root directory to the \Users\User1\Documents directory, type:
mklink /D \MyDocs \Users\User1\Documents
Also we can use junction.exe or linkd.exe to create symbolic link in windows 7,you can try them after put them to C:\windows\system32 if you have the interest.
