Hi Jyoerger, welcome to the Seven Forums.
You can't transfer installed software and programs simply by copying the Program Files folders. Sorry. You need to reinstall every program again after reinstalling Windows.
Same with user accounts. You need to recreate every user account. There is a method to transfer user account as they are using a program called Windows Easy Transfer
(WET). Using WET, you simply tell it on old computer / old installation which user accounts and files to backup, and then again using WET you transfer them to new computer / new installation.
In your case you have really messed up your new installation. The best thing for you to do now is to wipe PC again, to install Windows 7 again from scratch. Then you need to reinstall all your programs, recreate all user accounts and finally copy user files and folders from your backup to new user accounts. Because you already reinstalled, you can no longer use WET to transfer user accounts.
