I need some help with Windows XP installation. I had disabled system restore on all the hard drives. Later on just enabled the same back on C drive. So just in case if there is a problem I can restore the same back. After running disk cleanup I found that it is not able to get rid of old disk cleanup files. I am trying to clean it. The space consumed by the old system volume information is around 20mb. I just want to know that whether it is safe to get rid of the same.
