Restore Default Junctions

I recently changed my user name on Windows. Using some registry trickery I was also able to change my actual user folder. With the exception of a few programs that were using static pointers to my user folder (Dropbox), everything went well. But later I started getting errors from Windows Backup like this though.
Backup encountered a problem while backing up file C:\Users\ddaydj\Documents. Error:(The system cannot find the path specified. (0x80070003))
I was ignoring it for a while, but got tired of my backups having errors. After looking around my computer and doing some research, I realized my junctions that were created with the user profile, were still pointing at my old user folder (I did an article about junctions a while back). So I went ahead and made a script to go through and delete all the default junctions in my user folder and recreate them.

Below is the script I wrote. You can copy and paste it into notepad and save it as a .cmd file. It requires that you run it as an administrator, so if your user account is not an admin change the 3rd line where it says %USERPROFILE% to the path to your user folder (Example: C:\Users\ddaydj).

Edit: Well, I just learned a lot more about doing batch files. Below is an updated version of the script that should be significantly nicer to look at and easier to understand (not to mention 71% smaller). Also, if you want your My Games folder to redirect to Saved Games, remove the REM from line 17.

Edit #2: Turns out this wasn't what was causing my problems Windows Backup. My registry modifications to migrate my profile were incomplete and I also needed to change all the entries here to point to the new folder, HKU\SID\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders. The script is still helpful for cleaning up junctions though.
