You probably need to reinstall your programs from an original disk. In the case
of Remote Desktop Connection, you need to set it up on your new installation of Windows 8.
If you did not install the operating system as an upgrade, then windows 8 simply installed the OS
and did not connect your old programs to the new Windows 8 operating environment. You need to
use each of these programs installation programs to get them set up to work on the new operating
system. IF it is possible, you could try to remove your windows 8, rename windows.old to windows
then use your WINDOWS 7 disk to repair windows 7, or better yet, restore windows 7 from a
backup. { If you don't have a backup, you now know why you computer teacher says BACKUP,BACKUP, BACKUP! until you get tired of hearing it.
Then, once you have windows 7 up and running properly, you can try to install windows 8 as an upgrade.
You may find that Windows 7 is actually better. Windows 8 removed that START BUTTON and
replaced it with the "Metro" interface where you have to click on a desktop ICON to get the ordinary desktop {minus the start button} you were used to in Vista and 7.
