Chú ý là xóa trên win nhưng k phải xóa trên win. "UpperFliter" là key chỉ ra bộ lọc cho thiết bị. Class là các lớp thiết bị,Services là dịch vụ,Enum\root liệt kê các thiết bị của hệ thống(bao gồm cả thiết bị ảo), màn hình xanh lúc khởi động là do thằng này.

Hi vọng sẽ giúp đc các bạn 

Em hiện đang dùng chú Deep Freeze 6.2 và đã đặt pass cho nó rồi, mà Em muốn remove nó nhưng quên pass rồi làm sao bây giờ ! E kô muốn ghost hay cài lại Win đâu vì con PC nhà Em mỗi lần cài là mỗi lần khổ với nó hà ! Mong các sư huynh chỉ giúp tiểu đệ ! Thanks 1000 lần luôn !  

To start of the tutorial i have to say, that recently I'm busy playing the role of a network admin, and since the network needed some work, and the computers have deep-freeze on them i had to find a way to bypass it, because nobody knew the password(yeah...what a Nice job i have).
So this tutorial is not meant to be used to hack the system at your school, library or any other place which uses this software to protect the PC's.

So let's start.

Step I:
Setup the PC so that it boots from the CD, i think i don't have to say how that can be done

Step II:
Download Admin Pack from Winternals.com, you need a payed email address, they wont send you the link if you provide a free email address like @yahoo.com,@gmail.com and so on.

Step III:
Burn yourself a copy of ERD Commander 2005, you can use the wizard.

Step IV:
Boot from the CD and wait until ERD starts. Once started use regedit and navigate to:
HKLM\System\ControlSet001\Services\DepFrzLo
make a backup copy of that key, and then proceed to deleting everything except the "installpath" key
Once that is done, reboot the computer and start normally, now it will take abit more than usually but once Windows starts you will be happy to see that there is no deep-freeze started, and everything you do will remain there Unfortunately this method can't be used to uninstall Deep-Freeze, but it's good if you want to make a quick change and don't know the password

Step V:
If you want to restore deep-freeze, boot from the CD and use your backup You did make a backup didn't you?

I hope this helps someone, this method can't be found searching with google(trust me i searched allot for a way to bypass the password) so i think it's an asset
