The Advanced PC Tweaker version 4.1.0 has been released on September 27, 2008. This is a major update and we take it to 4.1.0 since there are lots of functions and integrated solutions that have been improved and packed in this new version. Basically, we have solved the issues with Vista compatibility, too aggressive registry repair capability on printer apps (e.g. HP all-in-one program), and conflicts with Microsoft .Net framework.
