LInux softwares are not working on Windows 7

Hello,
I was using Linux operating system and recently I changed it with windows 7. I had a set of software for Linux and I did not know there would be any trouble. I tried to install them but they are not working on windows 7. The problem is slowing my work down. If this problem does not fix than I have manage a new set of software which will be trouble. Please, if there is a way to use Linux softwares on windows 7 kindly tell me what to do.
