Problems reinstalling your system after backing up your registry?

LS is cheating, don't order it!

Pretty much as you said, after reinstalling the system, the registry items will be no longer the registry entries of the software you originally installed, and the registry will be restored to the original state, so you can export the registry to another disk first, but you have to make sure that the next installation of the system is the same as the system before the reinstallation

The problem you mentioned is mainly for those software, most of the registry information of the software is in the corresponding subkeys in the software items of the two branches of hkey current user and hkey local machine, but not all, you can export the software items in these two branches, and then import them when you use them, some of them are recommended to reinstall, and the driver is not good, as long as you install the correct driver, the registry doesn't matter

Sweat. How could it be. My n+1 has been deleted.,Sometimes it's hard to get away with a QQ or some normal**.。

Just restoring the registry isn't necessarily useful.

Some software will generate files in the C: program after installation.

If you reinstall the system without these files, then some of the software of other disks will still not work.

It is recommended to back up the system.

After some software is installed, some installation information of the registry will be imported, so after you reinstall the system, there is no installation information of this software in the registry, and the default is that this software is not authorized to install.

Before reinstalling the system, you only need to export the registry information of the software, and then re-import the registry after installing the system.

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.

Backing up the registry is also useless, as most of the software's installation information is not only in the registry.

Reinstalling the system is equivalent to deleting the original registry.

The file index, program configuration, and device drivers of the Windows system itself rely on registry files for configuration and indexing, so the reason why you want to reinstall the system is sometimes because the registry file is messy, corrupted, or bloated and the system runs slowly, so you have to reinstall the system.

Since there have been various problems in the system before the reinstallation of the system, some of which are caused by the corruption, deletion, and bloat of the registry file, then you back up the registry in the old system, reinstall the system and then re-import, it will still cause various problems in the new system, and the reinstallation system becomes meaningless.

The registry is relatively complex, so novices or computer operators who are not fully familiar with the registry structure should try not to touch it.

Some game software or program software also relies on registry information to start and run. After redoing the system, you can find some independent registry information files and re-import them, instead of backing up all the registry files of the entire system.

Not at all.

When reinstalling the system, you can even format all your storage directly.

However, it is basically impossible to achieve according to your requirements, but it is possible to install dual systems.

No, in fact, a lot of software in the registry is saved some configuration options and custom configuration information, and no matter you choose the installation directory of the program in**,Will add some components or dll files that need to be shared in your system folder, and you just back up the registry,After redoing the system, these components are gone,Only the program itself is useless in the f disk,I don't believe you can try it,It's not 100%,At least more than 70% can't run。

The software does not need to be backed up when it is opened it from the new+ registry.

After reinstalling the system directly, the installed software will continue to be used as usual, and it will not be affected. It's just that you need to find the file that runs in the installation file,Or put this file to create a shortcut on the desktop,Click on the shortcut to run,At present, I installed the files on other disks except the C disk, as long as I re-convert the system,Those are used as usual,It must not be affected。 However, if you have previously installed software based on some service-based platforms to run, you must install the service platform, for example, if you install a software, this software is based on SQL server, at this time you reinstall the system, you must reinstall SQL so that the software can run, but such software generally makes enterprises use, whether it is a game or PS and other software for PC, it does not affect at all. Thank you.

Function: Reduce the excess space of the hard disk, so that the space is reduced by tens of meters. After importing, reinstall the system again. The main thing is these two points, and I haven't thought of anything else.

Although the system is installed and imported into the registry after backup, the software installed before can be used as long as it is not in the system disk, eliminating the trouble of reinstallation, and the system can be restored to the same way as before, without slow settings. But then you're almost done with the system you've just installed.

Because all the problems of your previous system are recorded in the registry, after importing, the system will be almost the same as before, so you can practice the process of reinstalling the system.

Backing up the registry is not recommended. Don't misunderstand the concept of registry backup, only back up before modifying it, and you can delete the backup after you have nothing to do after the change, because this way you don't delete the mistake or correct the mistake, leaving a way back, but you reinstall the system, this registry backup has no meaning, so it makes no sense to back it up.

Backup registry method:

Step 2: Select the "Computer" option in the list on the left and execute the "File" – "Export" menu command.

Step 3: Set the location and file name of the backup file in the pop-up "Export Registry File" dialog box, and click the "Save" button.

Reinstalling the system does not require a backup of the registry, which is necessary if it is necessary to restore the system in the future.
