What is VAIO Improvement?

The VAIO Improvement program is pre-installed with various VAIO laptop models. It will re-theme various components of Windows to include Sony VAIO themes including screensavers, wallpapers and style and colors for menues, etc.. It also includes a number of tools and utilities with the PC to 'enhance' the user's experience including the Control Center, and updater, on-screen keyboard and hotkey utilities and more.


It is typically pre-installed with most new Sony computers. The most common release is, with over 98% of all installations currently using this version. During setup, the program registers itself to launch on boot through a Windows Schedule Task in order to automatically start-up. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The primary executable is named viuploader.exe. The setup package generally installs about 7 files and is usually about 3.94 MB (4,135,495 bytes).

This program is pre-installed on the PC

Pre-installed software such as this is usually included by default on the manufacturer's PC. Many OEM (original equipment manufacture) software that is included with a new PC is useful and in many cases required for the PC to function properly as in the case of various software drivers. However, some pre-installed software is optional and can be safely removed.
Some users and experts alike have reported that this program is considered bloatware or bundleware. Such software is optional and can be safely removed if you do not utilize the features of the progam.
Sony has been criticized for loading its VAIO laptops with bloatware, or ineffective and unrequested software that supposedly allows the user to immediately use the laptop for multimedia purposes. Sony also offers a Fresh start option in some countries which allows a new computer to be shipped only with a basic Windows operating system and very little trial software pre-installed.
  • It is usually licensed for use only on the Sony PC on which it was pre-installed.
  • It sometimes difficult for users to remove via the 'Uninstall a Program' feature in Windows.
