You should have access to the programs you installed, unless you specified
durring installation that you only wanted the program available to your user
account (which generally isn't the default option).
You can use the Windows Easy Transfer Wizard to save your documents,
settings, etc to a folder on your computer, and then load them in the new
user account you create - this will allow you to easily transition from your
old account to your new one.
