From time to time we recommend that you do some hacks in the registry either to fix Windows errors or to speed up your operating system. And every time we ask you to get a backup from the registry first, for your safety.
But for those who do not know, you can easily and quickly save a copy of it on your computer or anywhere else. registry.
First of all, you should know that the registry is a database that contains all the configuration options and settings for the Windows operating system. If you are infected by a virus, the registry is usually the first to infect. Therefore, except when we intentionally tease him, it is good to have a copy of it for security reasons.
It is also a good idea at some point to "clean up" the registry of old and useless information so that Windows becomes faster. Cleaning up junk program entries that have been removed can be done with the well-known Ccleaner program, along with other similar programs.
So let's make a copy of the Registry:
1. Press Win + R at the same time
2. Type regedit in the run window that will appear and then press the OK button
3. If you are prompted to "go back to this application to make changes to your computer" say Yes.
4. The registry window will appear. In the left column mark the name "Computer" and then at the top of the menu go to File -> Export.
5. The backup storage location selection window will appear. Check that "All" is selected in the "Export Range" box (if it is not, select it) and enter where it will save the backup. You can also choose to name the file as you wish.
6. Press the Save key.
You now have a backup of your registry. Remember to keep it in a safe place.
In case something goes wrong and you want to restore your registry, just double-click on your backup or go to File-> Import in the registry window and select it from there.
The above guide applies to Windows XP, Vista, 7 and 10.
