How does the registry open the computer registry?

Open mode

You can click start → run, enter "regedit" or "Regedit.exe", click OK. Registry Editor can actually find Windows\System in the system root directory.

If you can't open it, it may be locked, which is a common problem, and you can download additional software to edit the registry (such as "Super Bunny Magic Settings", "Registry Maintenance guru", "Registry Terminator (Regboy)", etc.

Win98/98se/me

Run input regedit.exe no permission restrictions
Win2000/xp
1. Start >> run. Input regedit
2. Start >> run. Input Regedt32
Win7
Win+r, regedit or regedt32

Two kinds of comparisons

The first method opens the same registry Editor as under Win98, and the same functionality, while using the second method to open Registry Editor can easily set permissions, it is recommended that network administrators use the 2nd method to open Registry Editor to modify the permission settings that need to be modified in order to avoid being maliciously modified by others.
Windows VISTA/7
1. Enter regedit in the Start menu search box and press ENTER. (Requires Administrator privileges)
2. Enter Regedit.exe in run (requires Administrator privileges)

Import a reg file to unlock the registry as follows:

Create a new text document that can be edited with Notepad from the system, which reads:
REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableRegistryTools" =dword:00000000

There is a blank line between the "REGEDIT4" line and the back line, and punctuation must be in English, pay special attention to quotes and colons, and then save with a. reg suffix, such as "Unlock.reg," and note that it is important to select "All Files" in "Save Type". Remember where this file is saved, and finally double-click the registry file such as "Unlock.reg" to import the registry.
