after reinstalling windows reclaim space

Thats not too many and they arent taking too much space. I'm really confused now. Do you want to delete some of these programs because you dont need them? If yes, just go ahead.

How did you reinstall Win7 if you have all of these programs left over?

There should be no programs left over if you reinstall Win7. Please clarify.

i installed those programs after reinstalling windows. i was referring to old program files which were hanging there without any registry entries. i'v deleted most of them.
i wanted to delete those files because they weren't useful or working anymore.
thanks for all the help.
