I keep on adding DisabledComponents REG DWORD to setup IPV4 precedence (required for some legacy applications) & Windows is deleting this key randomly after few shutdown restarts. Ie, the key remains there in the registry for couple of days and all of a sudden deleted during a cold reboot.
OS: Windows 10, 1903 (64Bit, Professional)
1st of all I thought of a possibility because I had CCleaner & the same is famous for deleting registry keys, so uninstalled & found the above said repeating. My laptop is fully updated with Windows Defender as ONE and only threat management software configured.
