Windows recreating old user account folder during software installs

Hi, I hope somebody can help.

I've created a new administrators account, and removed the old one, copying the user profile to the new account but changing the account name. Everything works fine, except now whenever I install a program, it recreates the previous user folder in C:\Users\(old username) to extract the installation files.

I'm wondering how I would go about changing the default directory to prevent this from happening, and whether there are any other problems similar to this that I might encounter?

Currently running Windows 7 Home Premium x64.

Many thanks,

Luke.

How did you go about removing the old account?

Windows ties a unique string of numbers to each user account within Windows. The best way to remove user profiles is from Advanced System Settings. To do this, type Advanced System Settings into the Start button search and hit enter. From there, click the Settings button under User Profiles. From here you can delete the profiles.
