If you are looking for third-party tools to back up your registry, there are plenty of options available. Acronis True Image is one of the most popular Windows backup programs and it comes with an easy-to-use registry backup option. Another popular tool is EaseUS Todo Backup Free, which lets you back up the entire registry or just selected sections.

No matter which tool you use, it is important to keep regular registry backups so that you can easily restore the registry in case of any issues or bad changes made by a program. This will help protect your computer from any potential harm and let you get back up and running quickly.
