Wrong method. The correct way to check the registry size is to click Start, Run and enter regedit. Open the Registry Editor, click the "My Computer" node at the top of the registry content tree on the left, that is, select the whole registry, then select File, Export, and select the storage path and file name to export the registry. At this time, you can check the size of the whole registry, which can't exceed several hundred meters! Ha ha laugh

At the same time, this method can be used to back up the registry to restore the changes to the system. As the registry is a very important part of a system, it is recommended not to change it casually.

Config is the abbreviation of configuration, which is full of system configuration files. It's big and normal, but it has little to do with the registry.
