What is a .TLS file?
The file extension .TLS stands for TuneUp Utilities Logon Screen. This type of file is used to customize the appearance of the logon screen on Windows computers. It is created and used by a program called Tune Styler, which is part of the TuneUp Utilities software suite. A .TLS file can include various elements such as a custom background image, different fonts, and unique buttons. When this file is used, it replaces the standard logon screen that you usually see when starting up your Windows computer with a new, customized version.
To open and use a .TLS file, you need to have the AVG PC TuneUp Unlimited software installed on your computer. This program allows you to apply the custom logon screen stored in the .TLS file to your system, enabling you to personalize the startup experience of your Windows PC.
