It is an all-in-one application that comes with dozens of options for fine-grained tuning of various Windows settings and features. Winaero Tweaker is a powerful system utility that supports Windows 7, Windows 8, Windows 8.1, Windows 10, and Windows 11 and includes hundreds of useful options. It was a good idea to create an all-in-one application which will include most options available in my standalone Winaero apps. I have created the initial version of Winaero Tweaker by merging years of development of my small free apps.
