Today early morning one of my friends called me for urgent help. He is working as a System Administrator for a small company and wants to disable copying files from working computer to USB drives (pen drives). I told him to disable the USB port and fix the issue. Then he said according to the company policy he cannot disable it. He wants the computer should read files from the USB drive but no file transfer to it from computer hard disk. So, in a nutshell, he wants to read files from the portable storage drive on his company computers but does not want to copy files from his company computer to the USB drive. He is confused that if it is possible to block writing files to the portable memory storage without preventing the PC from reading it.

I too at first confused with this strange company policy. Then I realize, it is very simple to do. We can enable write protection on USB by GP edit or Registry Edit. If Write Protect is enabled on Universal Serial Bus, the computer can read files…

Yesterday night my friend called me. His sister just finished her project work on her laptop and to protect the files she changed the password of her Laptop. After changing the password she is not able to log on to her Laptop. It is a Windows XP Laptop and only one user account is there. What she was telling is the Laptop is not accepting her new password and old password. She told me, tomorrow she should present the project in her college and there are no backup files. At first, we tried some possible passwords and they were not working. Then I told them to restart the Laptop and when the Laptop start booting press [F8] button. My intention was just to get the default Windows administrator account and hope they didn't set a password. They started booting their computer and get into the safe mode. They saw the hidden Windows admin account and log on to it[ Thanks to the guy who installed OS on her laptop as there is no password].
