For individual users to use computers at home, such security controls are sometimes unnecessary, but it is still useful for Internet cafes and public computer rooms managers and users to understand these security controls, allowing you to easily and easily control your computer and greatly reduce your maintenance work.
Disable Regedit using Register Editor
The registry is very dangerous for many users, especially for beginners. For safety, it is best to prohibit the registry editor from running, which is more important in public computer rooms, otherwise your machine will be changed to a mess if you accidentally.
Open the registry to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System. If you find that there is no System primary key under Policies, please create a new primary key under it, name System, and then create a new DWORD string value in the blank space on the right, with the name DisableRegistryTools, and modify its value?. After this modification, no one who uses this computer can run it to modify the registry, of course, you also include yourself. If you want to restore, please save the following code as a file and restart: REGEDIT4 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System] "DisableRegistryTools"=dword:000000000
Hide and disable the Control Panel
The control panel is the control center of the Windows system. It can modify many important things in the system such as device properties, file systems, security passwords, etc. Of course, you need to be careful of these. Open \\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System\Create value NoDispCPL and change the value to 1 (hexadecimal). No program is allowed
Open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer, create a new DWORD string value in the window on the right: "RestrictRun", and set its value to "1". This way we can prohibit running any programs in Windows 98. Modifying the registry allows users to use programs specified by you only
Open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer, create a new DWORD string value in the window on the right: "RestrictRun", and set its value to "1". Then add string values such as "1", "2", "3" under the primary key of RestrictRun, and then set the values of "1", "2", "3" and other strings to the program name you allow users to use. For example, if “1”, “2” and “3” are set to “1”, “2”, “3” respectively, then users can only use word, word board, and the Empire Age. In this way, your system will provide the greatest guarantee and can also restrict users from running unnecessary software.

Change IE's security password
You can set a password in the "Level Review" box of the "Content" option page of the "Internet Options" dialog box in IE. In this way, when the relevant page is displayed, a prompt message "Level Review does not allow viewing" will always appear, and then the exit command dialog box pops up, asking you to enter the guardian password. If the password is incorrect, browsing will be stopped. However, if you forget this password, you will not be able to browse it, and IE4.0 will not be able to remove the security password. At this time, you can only ask for help in the registry:
Open HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies, select the "Ratings" subkey under the Policies subkey, and press the Del key to delete it. Since the Key key value data under the Ratings subkey is an encrypted password, if this item is deleted, the password in IE will be removed.
Clear various historical records
Various historical records of users are retained in Windows 98 system, including recently opened documents, programs, searched files and usage on the network. When using a computer in a public computer room, for our personal safety needs, we need to delete these historical records, but the general deletion method is very unclear, so we have to ask the registry for help.
Open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer, delete the keys shown in the table, clear the content in Windows\Recent, and refresh the document menu, so that your records can be removed.
The following are the table entries in this directory: Location Location in the registry Documents menu RecentDocs Run dialog RunMRU Find Files dialog Doc Find Spec MRU Find Computer dialog FindComputerMRU
The safety of public computer rooms and system stability are very important. Here we are just the most basic protection functions. If you want to achieve good protection, you must turn to other management software. Here we are just a little help.
