Although the registry can be modified by manual editing, this method can be very dangerous, because even a small error can cause the system to crash or fail to start. Therefore, we suggest that you use professional registry editing tools to modify the registry. The following are the detailed steps:
Step 1: Back up the current registry.
Before starting to modify, be sure to back up the current registry so that you can restore the previous settings when there is a problem. You can use WindowsRegistryEditor for backup. On Windows 10/8/7, press Windows key +R to open the running dialog box, enter regedit, and press enter to open WindowsRegistryEditor. Then, select the File menu, click Export, and save it in a safe place.
Step 2: Open Registry Editor
After opening the Windows Registry Editor, you can see five menus: File, Edit, View, Favorites and Help. In these menus, you can add, modify or delete registry keys and values. In the left panel, you can see some registry keys named "HKEY_", which are different branches of the registry.
Step 3: Select the registry key to modify.
Select the registry key to modify in the left panel. For example, if you want to modify the default browser settings, you need to go to the HKEY _ Current _ User \ Software \ Class \ command.
Step 4: Modify the registry value.
Double-click the registry key you want to modify, and then change its value. For example, if you want to change the default browser, you need to change the default value item. Double-click the default value item and change its contents to the path of the new browser.
Step 5: Save the changes and close the Registry Editor.
When you have made the required changes, save the changes and close the Windows Registry Editor.

Modifying the Windows registry is an advanced task that needs to be carefully completed. Please make sure that the current registry is backed up before doing anything. In addition, if you are not sure about changing a part of the registry, please consult a professional first.
