Yes. You can do an in-place Upgrade with your full-retail version of Ultimate.
I would uninstall all of the junk programs from the Control Panel>Programs and Features, delete any folders for them left in C: Program Files, then clean them out of the Registry's (regedit) HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE Software keys by right clicking and deleting. Ask here for help. Set a system restore point.
Then use the CCleaner disk and registry tabs to clean up the debris, and the free (state of the art) Auslogics disk/registry defraggers to put it in flawless order. Or the Windows Defragger if you must.
Run the DVD from the desktop and do an in-place Upgrade. Back up your files as this can fail and does regularly. Taking the steps above will reduce corruption but there will still be some level.
Cheers and best of luck!
