We are much familiar with windows operating system, there are lot of vulnerability’s in Microsoft’s windows operating system. I am discussing here one from them might be you are all unaware of this. In our college defreeze software is installed to prevent from attacks by virus or unauthorized access. But this weakness of operating system does not protected by defreeze completely, because it restore data after operating system.
Windows service pack 2 allows normal user such as “student” in our college(which restricted for complete use) to create an new account as administrator, but we have to create account in some different way stated in following stapes:
