Method 1 – Restore your registry using registry back-up

How to create a registry back-up in Windows 10

  1. Type regedit in the Windows search bar and select it from the list of results.8
  2. This will open the Registry Editor dialog box. It is the place where you can modify, delete, change and back-up all the registers.
  3. Now is your decision what you want to save. You can back-up the entire registry, or you can back-up only a part, if you know where you will be working. We recommend you to back-up the whole registry because in this way you are sure that everything works in this state and you will not have to create every time a copy for each edited register.
  4. To back-up the whole registry right-click on the Computer section from the left table of the Registry Editor interface.
  5. Select the Export feature. This will create a .reg file where you have all the registry from that moment.9
  6. Save the file in a known location (like Desktop or Documents) to be sure you can find it easily.
  7. Check the place where you saved the registry. If the file is there, we can continue to the next stage, otherwise read more carefully the steps from above and try again.

How to restore your Windows registry

  1. Locate the back-up file of your registry. If you have problems of finding it, check in the Documents folder (the folder where is saved automatically) for a .reg. The icon looks similar with a blue broken Rubik’s cube.
  2. Double-click on the .reg file to open it. Depending on the configuration of your operating system, you may receive a dialog-box where you have to allow the application to make changes to your computer. Click on the Yes button in this case to start the restore process.
  3. You will receive an attention dialog-box where you are informed that the following actions may cause your components to not work properly. If this file is created by yourself, then it will be safe to run the process, otherwise make sure that the source of the file is safe.
  4. Click on the Yes.
  5. Assuming that your back-up file was imported correctly, you will receive a notification where you are informed that the file was successfully added to your registry.
  6. Click on the OK button of that dialog-box. Now you can delete the back-up file if you consider that you will not need it in the future.
  7. Restart your system to complete the configuration.
