Illustration: Method for restoring 6.0 from an ice point (1)

I. First, let's talk about how freezing points work.If you have no patience, you can jump to the second part to learn how to restore the ice point by 6.0 .)

Many people may have read the Post "DeepFreeze freezing point Principle" widely circulated on the Internet. Why should I reiterate its principle again? Because I am a technical engineer, deep understanding of the theoretical significance of practice, do not understand the nature of things, technology can always stay at the level of follow; in addition, I think this post is not clear, and some places are still misleading.

Freezing Point is different from other restoration software such as restoration Genie and three-way one-key recovery). It does not take control of the I0 of the nanqiao chip or control the INT13 interruption of the hard disk, it does not rewrite the MBR Master Boot Record of the hard disk ). The restoration software of the MBR, such as the recovery Genie and three-way one-click recovery, which uses the hard disk to rewrite the hard disk, partially implements the restoration function before the operating system is loaded, the freezing point is to use the driver to add the kernel module of the operating system to implement its restoration function. It must be attached to the original system. Once it enters another system, its Restoration function becomes invalid. It has a very high loading priority, and cannot be disabled or deleted after the current system is loaded. The kernel driver of freezing point is described through software:

There is no "replacing the original driver with your own hard drive program" at freezing point, and it has a similar relationship with the original hard drive, that is to say, all access to the hard disk must first pass through its "filter" and then be handed over to the original drive of the hard disk for restoration. This technology is called "filter driver ". Verify the detailed analysis of the hard disk and partition driver files:

As a character access device, the mouse and keyboard are also monitored by freezing points:

Speaking of this, you may have come up with a method to crack the freezing point, that is, to uninstall the freezing point kernel driver, but this is not enough. We have to solve the relationship between freezing point and the upper and lower layers of the original device driver, someone may have tried to delete Deepfrz directly. sys File and directly or indirectly clear or disable the registry key:

The HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ DeepFrz method encountered a blue screen experience because the driver was not unlocked. Below I will provide a method to restore the ice point to 6.0. Of course, as long as you understand its principles, there are various methods.
