I have a Windows vista Home edition and will be upgrading to Windows 7 professional. Windows 7 professional doesn't allow an upgrade path from vista home so i'll need to do a clean install. My question is if there is some way to make a backup of my programs and then just transfer them into windows 7 once its installed. A lot of these programs/applications i've lost the install disk or the key that was needed to run the programs and i'd like to just skip the hassle and headache of reinstalling all my programs if necessary. I was wondering if i could just make a back up on a portable harddrive and then move the program system files into the new system. OR partition my current harddrive with half vista (C drive) half window 7( D drive) (idk if this is even possible) then copy and paste the files from the C drive into the D drive and finally erase C drive (vista). Finally I would move all of those working applications and windows 7 files back into the now empty C drive. I dont know if any of this is possible or if I should just prepare to buy the software again, etc. PLEASE HELP!
