How to connect to child window of control.exe in pywinauto

I am able to open Control panel through below code, able to get dump_tree of All Control Panel Items too. My intension is below once control panel. When I tried to click on Network and sharing Center getting below error. Could anyone help on this

My intension: -In the left panel of Network and sharing Center, open Change Advanced sharing setting -Under network discovery, Click on ‘Turn off network discovery” option. -Click “Save Changes” -Go to Tools->Folder Options->View. -Check 'Hide protected operating system files -Close to save

My code:

Application().start(r'control.exe', wait_for_idle=False)
app = Application(backend="uia").connect(title="All Control Panel Items", timeout=10)
main_window = app.window(title="All Control Panel Items")
#main_window.dump_tree()
Network=main_window.child_window(title="Network and Sharing Center", control_type="Hyperlink").select()
Network.select() # it expands the subtree

Error getting:

pywinauto.uia_defines.NoPatternInterfaceError

Solution

NoPatternInterfaceError means that this action is not implemented on the app side. SelectionItem pattern is usually available for ListItem or TreeItem elements.

For hyperlink use method .invoke().
