One: Internet cafes restrict access to local hard disks.
Generally speaking, there are two possibilities, one is simply hiding, and the other is not only hiding but also prohibiting access. According to the different operating systems, I found that 98 system is simply hidden, while XP or 2K system will make access restrictions.
For simple concealment, it is very simple to crack. Using batch files, you can:
Create (or open) a notepad file and enter:
Start c:\
Then save it as a bat suffix, and the file name can be taken at will, but the suffix name must be bat. For example, 123.bat is a simple batch file.
Double-click this bat batch file, and the running effect is to open disk C. Let's briefly explain the meaning of this batch command start. In fact, literally, this command is equivalent to "run". For example, if you want to run a command prompt, you can also enter: start command.
And this start is actually a dos command. In fact, batch files can be simply understood as files that can automatically run dos commands. Of course, the function of batch processing is not that simple, just understand it!
If it is an XP or 2K system, run the batch file above and prompt "This operation has been cancelled due to the limitation of this computer. Please contact your system administrator. In other words, no access. You can change the settings from Group Policy.
Similarly, because Internet cafes generally don't run it for you and the system disk is limited, we can only run it with batch files and reopen the group policy.
Enter this time:
Start gpedit.msc
Then save it as a bat file, and gpedit.msc is a group policy. Open Group Policy, and there is an option to "block access to this drive from my computer" in the directory of "User Configuration-Administrative Templates -Windows Components -Windows Explorer". Ha ha, you see, just set it as disabled. Then use start c:\ to open drive C. Here you will find that there are many related restrictions in the group policy, such as the hidden drive, which you can set. Hehe, I won't talk too much about this for the time being.
Two: the file was hidden, and I entered the local hard disk and found that there was no file at all.
Solve, different degrees of restrictions are divided into the following different degrees to solve:
1: The simplest thing is that there is an option to display all files directly in "Folder Options-View-".Click it to display all files.
The folder option of 2: 98 is under the view menu, and the folder option of 2K and XP is under the tools menu. Generally, 98 folder options will exist, while XP folder options can be hidden in group policy. For XP, open the group policy "User Configuration-Management Templates -Windows Components -Windows Explorer" and set the option "Delete folder option from tools menu" to disable, and it will be done.
Of course, the 98 system can also remove that folder option, so that we can display it and open the registry. According to common sense, this is the registry key value of folder option in HKEY _ local _ machine \ software \ Microsoft \ Windows \ currentversion \ Explorer \ advanced \ folder \. But if 98 deletes all this (I have met such a BT webmaster ...), I can't change it if I want to, but I can only import the registry file to repair it.
Because there are a lot of contents in the registry, I won't copy them here. Just download the attachment folder. Reg "and import directly. Now you can set it directly.
3: What should I do if I find that I don't "show all files" when I open the folder option? Don't worry, the same reason is limited to the registry. If you import the entire registry file as in step 2, this will not happen.
If XP uses group policy to display folder options, just create a new notepad, enter the following red text, and then save it as123.reg.
Registry 4
[HKEY _ LOCAL _ MACHINE \ Software \ Microsoft \ Windows \ current version \ explorer \ Advanced \ Folder \ Hidden \ SHOWALL]
"RegPath"=" Software \ \ Microsoft \ \ Windows \ \ Current version \ \ Explorer \ \ Advanced "
"Text"=" Show all files "
" Type"="radio "
" checked value " = dword:0000000 1
" ValueName"="Hidden "
"Default value" =dword:00000000
" HKeyRoot"=dword:8000000 1
" HelpID " = " update . hlp # 5 1 105 "
Then double-click the file and import it into the registry.
4. The above three situations are aimed at folder options to break the restrictions, and I believe most of the problems should be solved. But there are other methods, that is, using the DOS command attrib to delete the hidden attributes of the file, or even delete the system attributes. However, one disadvantage of this system is that you have to know in advance what files the system has (in fact, this is not difficult, the system only has a few folders).
The specific operation steps are as follows:
First open the command prompt. We should get used to using the command prompt as the running menu. How to open a command prompt? Oh, the same reason is that the system of 98 uses "start command" and the system of XP uses "start cmd" to save it as a batch file to run ... Let's not talk about this reason. Inference is the most basic learning ability.
Then enter at the command prompt:
Attribute target file or folder -h
This will delete the hidden properties of the file or folder. The parameter "-"indicates deletion, and "h" is a hidden attribute parameter. Similarly, if you want to hide a file, you can use "+h".
Attrib This command can also be used like this:
Attribute *. * -h
Display all files, but remember, this can't display all folders ... it should be that there is no function of displaying all folders in batches ... just look at the basic knowledge on the network. Not too much.
Three: the registry is limited. There are two other situations.
1。 When we open regedit, the system prompts to prohibit the use of the registry. This means that although we can't open the Registry Editor, we can still modify and edit the Registry by importing the reg file. The ban can also be lifted by importing. The specific method is very simple, just look for it online, that is, write a reg file with the following contents in red font:
Registry 4
[HKEY _ Current _ User \ Software \ Microsoft \ Windows \ Current Version \ Policy \ System]
" DisableRegistryTools " = dword:00000000
This will open the Registry Editor.
2。 When you want to import the registry file, you will be prompted that "the registry has been disabled by the administrator, please contact the system administrator", which should be XP instead of 98 operating system. The solution is also in Group Policy.
Open the group policy "User Configuration-Management Template-System", and there is a "Prevent Access to Registry Editing Tool" under this directory. Just set it to disabled.
Four: download restrictions.
I have encountered situations that I can't handle, so I didn't want to talk about them at first. Because if you open an Internet cafe and even restrict downloading, then the network administrator is probably a garbage idiot. I would never go to such an internet cafe. Without much gossip, here are several possible ways to crack the download restrictions.
1: The easiest way to use online installation tools, online downloads and so on. Or QQ network hard disk download TT installation, use TT's own download tool to download.
However, the QQ network hard disk is blocked, which is a bit troublesome and difficult to handle. If the other party modifies the QQ dll file to achieve this goal, you have to find the modified data you want to close yourself. I didn't do it. If only the system settings of QQ are hidden, we can break them ourselves, and open the QQ menu "Personal Settings-System Settings-Panel Settings-System Panel" where we can set the relevant panels to hide or display, but I guess Internet cafes are now modifying dll files to completely delete the network hard disk, so this move is not effective!
2. If the online installation control cannot run due to the setting of Internet options during the online installation, you need to set it in Internet options. However, Internet cafes generally limit the setting of Internet access options. To break this restriction, you can enter the system installation directory. Generally, it is the file c:\windows\system(XP is system32)inetcpl.cpl, which is the setting file of Internet options.
If it is an Internet cafe in Vientiane, the file name will be changed to inetcpl.cpp Just change the suffix to cpl and you can open it! (When you get here, don't tell me you can't get into the system disk ... -_-bb! )
Turn on the Internet option, in fact, you can make a download restriction here, that is, "security-Internet access-custom level-download". You can set download prohibition and download permission here. If it's just this restriction, you can already interrupt the download. But it's not that simple now. Now, let's remove the restriction of running the control online and set it as enabled in "Security-Internet-Custom Level -ActiveX Controls and Plug-ins".
And if this still doesn't work, and the download restriction can't be lifted, you can consider whether the registry has been modified. I can't write all the keys of the online registry myself, because I once read an article saying that it is a waste of space to download many keys, so everyone should learn to search by themselves. Sometimes it is also true that the restrictions of Internet cafes cannot be broken manually. After all, people use software to make so many restrictions ... hehe!
