How to delete regIstry keys Windows 11 - UMA Technology (external Link not affiliated with HMS, take care)

1. First thing to check in the registry is to search for "Talk2m-eCatcher" in the registry key HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Network\

If you find one entry, delete the parent node (with the Big ID -> See here:)

2. If you do not find any "Talk2m-eCatcher" values or the problem persists, then it is probably because there is one entry in the protected key HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\NetworkSetup2.

If you click this key, you'll get an error message that the access is denied. This also explains why there is no output when you search for the value "Talk2m-eCatcher" in the whole registry.
One method to access this registry is to open the "regedit" using this "Advanced Run tool" available on https://www.nirsoft.net/utils/advanced_run.html. (external Link not affiliated with HMS take care)
