Well, you said that you cursor would move perfectly until you are going to run some software? OK, there are some tips you can follow.
The first thing to do is check for any button on your keyboard which has an icon that looks like a touchpad with a line through it. Press it and see if the cursor starts moving again.
To check if your trackpad has been disabled in Windows, click the Start button, type ‘mouse’ in the search field, and then select Mouse (or Mouse settings) from the search results. Simply click the Enable button to turn on your TouchPad.
