What is the function of the F8 key when the WinXP system changes startup?

F1 to F12 are function keys in the Windows system, but many users know little about the specific role of these function keys, or just know a part of them. What Xiaobian brought to you today is, what is the role of the F8 key when the WinXP system changes and starts?

F8 key role:

First, prohibit Windows XP from entering safe mode to disable security mode, restrict restricted users to modify the registry

By modifying the registry, Prevent users from entering the security mode of Windows XP with command line, avoiding others using the net user command to modify other users' passwords in safe mode, and restricting restricted users from accessing and modifying the registry to prevent others from modifying the registry to start safe mode.

Log in to Windows XP using an administrator-level account, enter “regedit” in the “Run” window, open the Registry Editor, find the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSafeBoot key, and “Minimal” and&ldquo under SafeBoot ;Network” item, renamed to "Minimal1" and "Network1" or other names different from the original key value. After the modification is completed, others press F8 to enter any security mode at startup, and the system will automatically restart.

In the Registry Editor, select HKEY_LOCAL _MACHINE, right click, select menu "Permissions", open the "HKEY_ LOCAL_MACHINE permissions" window, select “Users”, check “ "User's permission" under the "Read" item. This will prevent the normal user from modifying the registry to restore the security mode to normal.

Second, find the MSDOS.SYS file to edit it. Find C: MSDOS.SYS”, open it with your notebook, and add the following lines to the [option] section of the file:

“BootMulti=0”:Set the system to not be able to multi-boot ;“BootGUI=1”: directly enter the WIN graphical user interface at startup

“BootDelay=0”: set at startup "Staring windows." . . . . . . . ” Information stay time is 0 seconds: "BootKeys": set F4, F5, F6, F8 function failure during startup

Tip: Msdos.sys is implicit, read-only file, in resources You can see the file in the manager's Tools menu by selecting “View/Folder Options/Options/Show All Files”. When modifying a file, please remove the read-only attribute in the file attribute to modify it.

After this modification, press the “F8” key at boot time and there will be no Windows startup menu.

The above is the role of the F8 key when the WinXP system changes startup. When we need it, we can use the F8 key to make our operation easier.
