Bd Total Security 2010 Repairing

Hello,


Tthis is just a question I would like to ask. I was going through the user's guide. At one point where it described the repairing feature of BD, I read like this:


Repair - to re-install all program components installed by the previous setup.


If you choose to repair BitDefender, a new window will appear. Click Repair to start the repairing process.


Restart the computer when prompted and, afterwards, click Install to reinstall BitDefender Total Security 2010.


Once the installation process is completed, a new window will appear. Click Finish.


Remove - to remove all installed components.


Note


We recommend that you choose Remove for a clean re-installation.


The last line here says that if you want to reinstall the product, it is better to remove and reinstall, rather than repairing. Why?


What are the disadvantages of performing the repairing option?


Thanks.
