If you do not format your hard drive, product activation information should stay on your computer even if you reinstall Windows or other applications. You will not need to reactivate the software unless you have changed the hardware configuration of your computer.

If you do format your hard drive (formatting clears all information off of your hard drive) or if you alter the hardware configuration of your computer, you will need to reactivate the software.

It is up to you to contact Microsoft and resolve any activation issues. The university cannot intervene on your behalf and cannot provide you with additional product keys.
