Cancel viewing source files of IE associated with ultraedit

Cancel viewing source files of IE associated with ultraedit The ultraedit software was installed once, and I hurt it once. During the installation, it actually tampered with the options for viewing the webpage source file.
The default viewer of Internet Explorer is still very good. Although it is clear and beautiful, although it cannot be edited, it is quite comfortable to use.
The modification method is also very simple:
Note table:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ View Source editor \ editor name
Change the default key value on the right to c: \ windows \ system32 \ notepad.exe.
