Before version 0.6.7, the Installer deactivated the system’s DNS Cache Service in order to gain system integration for the Portmaster. This did break/impair some other software that depend on special functionality of said service. Since then we implemented a better approach for more stable system integration which you can read all about in this devlog
The deactivation of the system’s DNS Cache Service was done by setting the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dnscache
-> Start
from 2
to 4
and rebooting. Updating the Portmaster to 0.6.7 will revert this change accordingly while any new installs will not touch the registry key at all.
