How do I back up the registry and how can I back up the registry?

1.Compare changes to the registry using the FC Detection Software.

In order to achieve the "comparison", first, on your own computer (or any computer without a fault), the registry is "exported" with the file name "c: ; Then open the "Internet Options" window of IE, click the "Content" tab, and click "Settings General Change Password" in turn, and the "Create Supervisor Password" dialog box pops up. Enter the password to save the settings.

Hehe, I wanted to set up a "virtual environment" to assist in reconnaissance!

Since you just saved the password to quit, you haven't done anything else since you last saved the registry, so quickly export the registry again (assuming the file name is "c:.").

Now it's time for comparison! Since you don't have a professional registry comparison tool on hand, just use the command prompt "Let's do it." Its usage is simple:

Enter the MSDOS mode and enter fc c: c:.

However, it seems that the screen flashes and passes! 555 How do I leave the display result behind? "Redirects"!

Thinking of this, change the command to "fc c: c:."

That's it.

Open the "C: file" in Notepad, and after careful identification and comparative analysis, finally lock your eyes on the primary key of "hkey local machine software Microsoft Windows CurrentVersion Policies Ratings", and it is obvious that there is an extra item named "key" in the file.

Hurry back to the registry, find the key, and delete the item "key", and go back to IE to check, the problem has been solved.

Friendly reminder: don't underestimate some of the gadgets under DOS, in the case of no better tool available, maybe this is the best tool. If you use this method, you can solve many difficult problems related to the registry.

2.use"Registry Comparison Tool"Software:

A computer's registry is an important database that stores system and software configuration information, and if incorrectly modified or deleted, it can cause the system to malfunction or fail to boot. To prevent this, we can back up the registry before changing it, or use the system restore function to restore the registry to its previous state. Here's how to do it:

1.Back up the registry: Open the "Run" window, type "regedit" and press enter to enter the registry.

In the tree structure on the left, select the branch you want to back up, for example, "hkey local machine". Then click the "File" menu, select "Export", in the pop-up dialog box, select a save location and file name, and click the "Save" button. This completes the backup of the registry.

2.Restore the registry: If you need to restore the registry, there are two ways to do it.

One is to use the backup file, double-click the file you just saved, and follow the prompts to confirm and import. The other is to use the System Restore feature, open the "Control Panel", select "System and Security", and then "System". In the options on the left, click on "System Protection" to enter the System Properties window.

In the "System Protection" tab, click the "System Restore" button to start the System Restore Wizard. Follow the wizard's prompts to select a restore point, which is the system snapshot you created earlier, and then click the "Next" and "Finish" buttons. The system automatically reboots and reverts to the state of the restore point.

Note: When performing registry backups and restores, close all running programs and make sure that there is sufficient power or is plugged in. Also, before restoring the registry, it's a good idea to scan your computer for viruses or malware infections to avoid further damage.
