I have kept those ProgramData folders in C: on every computer. Some badly coded applications don't check variable %ProgramData% to see where information should be stored. In my case, this laptop I'm using now which got a fresh install early October, two applications have stored information on this original ProgramData folder: Skype to its own C:\ProgramData\Skype subfolder, and virtual disk application Gizmo under C:\ProgramData\Microsoft\Windows\Gizmo subfolder.
That Skype surprised me a bit. I had thought Skype would really be coded using variables instead of absolute file locations, but as it seems to be, I was wrong. I remember seeing same kind of bad programming back in XP's time quite often; my last XP was a Finnish one, Program Files folder was named in Finnish Ohjelmatiedostot. Because some coders did not use variables to determine default install locations, using absolute file locations instead and of course assuming I'm using an English XP if installing English application, or German XP if installing German application, I ended up having three Program Files folders: original Finnish Ohjelmatiedostot, English Program Files and German Programmdateien.
Just hide the folder and let it be there. It does no harm and never grows to be disturbing big. Total size of the "original" ProgramData folder in this laptop's C: drive ATM is 615 KB in 9 files, compared to my "new" and actual ProgramData folder in D:, which has ATM 10.5 GB in 45,899 files. I simply see no harm to let it be there.
