[Original] Methods for Improving the closure of polar domain electronic classrooms during VC operation

This article will talk about the materials and methods, specifically implementing and cracking the Lenovo hard disk protection system password in (below), the method for cracking the Lenovo hard disk protection system (delete it) is very simple, you can use a hard disk to protect the CMK, but it is very troublesome to recover. I don't know if this method is effective (use the 360 system first aid kit to back up the MBR in the normal computer of the recovery card, I have never tried to recover the backup MBR on a cracked computer. I need to know how the hard disk protection card is working. If it is not just clearing the MBR, find a repair shop, this method is somewhat risky. Of course, we also mentioned how to crack the Lenovo hard disk protection system password in (below). In addition, this experiment is only performed in Windows XP.

There is a comprehensive practical activity class in the school. Everyone can report on the activity based on their hobbies. I reported a computer creation, but the class was very depressing. School Computer Monitoring and restoration configuration: (monitoring software) Polar domain electronic classroom V6 2007 deluxe edition, some machine rooms also have Lenovo network control tools, but our machine room does not. (Restoration software) Lenovo hard disk protection system.

As I entered the topic, it was not a problem to watch the screen daze every day. After all, some of the content was quite simple, so I thought of cracking the password of the geek classroom. According to information on the Internet, the uninstallpasswd key value in [HKEY_LOCAL_MACHINE \ SOFTWARE \ topdomain \ e-learning class standard \ 1.00] of the polar domain electronic classroom is the plaintext password. I tried and succeeded, so I broke the password and went to the settings. Then I had a good time. I disabled the option "prevent students from shutting down this process" and click "OK". Now you can close it in Windows Task Manager. (Task manager banned when the solution, source, Baidu experience: http://jingyan.baidu.com/article/00a07f3889107082d028dc0f.html)

But now there is another problem: Isn't it too troublesome? How nice it would be to exit the polar domain electronic classroom at any time in the so-called "screen broadcasting" of the teacher, so we have to move into this way now. I found some information on the Internet, saying that the key CTRL and shift cannot be blocked in the polar domain classroom. This is easy to do, because 5 shift keys can enable the Windows auxiliary function-sticky key. In addition, the students often suffer harm in the Information Technology Lesson. When the teacher controls the computer, he presses shift for five times. The result is a window that cannot be closed (because it is being controlled ). We can use the sticky key function to close the teacher's geek electronic classroom and the annoying "screen broadcast window ". (For more information, see http://wenwen.soso.com/z/1695572886.htm. Press shift 5 to start the sticky key. You need to enable it before starting it. Needless to say)

Speaking of this, you should know what to do. We can actually replace the sticky key program with our own program. The program name of the sticky key is sethc.exe, which is located under c: \ windows \ system32 \ and backed up under c: \ windows \ system32 \ dllcache, this backup is a matter of Windows File Protection. The "dllcache" in win7 is a C: \ WINDOWS \ winsxs \ folder, but the storage method is obviously different. It has many more folders.

In the next section, we will start to use the C ++ language to write the program to close the polar domain electronic classroom (one sentence: System ("taskkill-F-im studentmain.exe ");), we also discuss how to crack the Lenovo hard disk protection system password. We can tell you that the Lenovo hard disk protection system password is in MBR.
