I have few windows software. I want you to test them on your friends/client's computers, when you go to their place for any computer work.
* Remember: If you are only a online worker, this job is not for you.
If you are a hardware/software engineer, system installing person in homes or offices near you, you can do this job. They are windows desktop software. (File manager, zipper, media player etc.) Just few minutes to install & Test whether they run smooth.
