Sau khi khởi động lại máy bạn sẽ thấy biểu tượng (icon) của DF trên Taskbar. Nhấn Shift và nhấp kép chuột trái vào icon này sẽ có bảng thông báo nhập mật khẩu bảo vệ chương trình (tránh để người khác vô hiệu hoá nó, bạn phải nhớ pass này!). Sau đó bạn sẽ thấy giao diện của DF gồm 2 tag là Boot Control và Password.
Trong thẻ Boot Control, để bảo vệ phân vùng C bạn chọn Boot Frozen, ngược lại để vô hiệu hoá DF thì chọn Boot Thawed. Sau khi chọn xong phải khởi động lại máy để thay đổi có hiệu lực. Có thể chọn vô hiệu hoá DF sau n lần khởi động (Boot Thawed on next …… restart) trong tag này.
Còn thẻ Password để bạn đổi lại password thôi.
Như vây để update chương trình chống virus cài trên ổ C hay bản vá Win,… chẳng hạn thì bạn chọn Boot Thawed rồi update, sau đó để bảo vệ bạn chọn Boot Frozen.

Deep Freeze helps eliminate workstation damage and downtime by making computer configurations indestructible. Once Deep Freeze is installed on a workstation, any changes made to the computer—regardless of whether they are accidental or malicious—are never permanent. Deep Freeze provides immediate immunity from many of the problems that plague computers today—inevitable configuration drift, accidental system misconfiguration, malicious software activity, and incidental system degradation.
Deep Freeze ensures computers are absolutely bulletproof, even when users have full access to system software and settings. Users get to enjoy a pristine and unrestricted computing experience, while IT personnel are freed from tedious helpdesk requests, constant system maintenance, and continuous configuration drift.
Balancing Security with Productivity
Deep Freeze is the only solution that effectively balances workstation security with user productivity. By mapping user and application data to a Thawed (unprotected) partition or drive, users are able to store their documents, pictures, music, etc., while still enjoying the total system consistency that Deep Freeze offers.
Flexible Resiliency
Deep Freeze offers flexible scheduling options that enable IT administrators to easily create automated update and maintenance periods. Schedule Deep Freeze to allow system and virus definition updates to occur from predefined times—either with the Deep Freeze Enterprise Console or using your preferred third-party desktop management solution.
Visit the Key Features page for a full listing of Deep Freeze’s capabilities and options for the two Windows editions: Standard and Enterprise. Mac OS X, Linux, and Windows Server editions are also available.

Education Corporate & Government Hospitality Libraries
Education Corporate/Government Hospitality Libraries
Education
Computers in education environments are among the toughest IT environments to manage and secure. The large number of daily users, the limited resources of on-site staff, and the immense number of computers and labs that technology personnel must manage all come together to create an IT ‘perfect storm’. IT personnel cannot afford to have computer systems down for long–students use computers in schools to conduct research and complete assignments; instructors need computers to record grades and organize their lessons; administrative staff need their workstations to complete their job function.
Computer Labs
Deep Freeze makes it easy for IT administrators to create bulletproof computer labs that deliver trouble-free computing to instructors and students. Deep Freeze ensures that students are able to use public access computers with the assurance that their session will be free from accidental system misconfiguration, malicious software activity, and incidental system degradation. Personal information is never retained by the computer, which means IT personnel don’t need to worry about desktop computers becoming congested with student projects and files. Computing environments become easier to manage, and expensive computer assets are kept running at 100% capacity.
Deep Freeze’s ability to prevent stability degradation ensures that scholastic computer labs are able to provide the same experience over and over again regardless of the user on the desktop–an important prerequisite to successfully teaching a classroom concept.
Administrative Machines
Deep Freeze is not just for student machines; it can also be used on instructor and employee computers. Since Deep Freeze offers flexible options for saving user data, it becomes easy to secure a workstation with total resiliency while still enabling users to save their work. Instructors and staff enjoy the assurance of knowing their computers will never fail them, and IT personnel are freed from having to deal with tedious helpdesk requests.
