Vista4Experts

Computer users who work with the Windows operating system on a day-to-day basis usually reach a certain point when modifying the OS behavior becomes a priority.
Microsoft Vista users can turn to Vista4Experts, a lightweight, free and portable tool that can make some changes to the operating system, with just a few clicks.
Thanks to the fact that installation is not required, you can store Vista4Experts on an external device (like a USB flash drive) and directly run its executable file on any computer that supports Microsoft Vista.
Therefore, the system registry does not receive new entries and you cannot find leftover items after removing the tool.
The interface of the app is based on a standard window in which you can disable the User Account Control, Security Center notifications (which appear after disabling the UAC), Windows Defender's daily automatic scan, the File Indexing Service (which is usually time-consuming) and balloon tips.
But you can also turn off Windows automatic updates, disable Aero, SuperFetch and the Windows Sidebar, as well as add MSDN (Microsoft Developer Network Platforms) to the Internet Explorer search bar and set it as the web browser's default search engine.
By accessing the context menu, you can check, uncheck or disable items. The terms may be a little confusing here: 'uncheck' means disabling the respective option while 'disable' refers to leaving the settings to default. Plus, you can enable, disable or invert all actions.
The lightweight app requires a low amount of CPU and system memory. It is stable, has a good response time and provides users with information about some of the actions it can perform. Vista4Experts did not freeze, crash or pop up errors throughout our testing. The tool offers some straightforward solutions to Windows Vista settings.
