Sample scan

ScanCircle is a diagnostic tool for your computer. It compares the hardware, drivers, software, processes and other characteristics of your computer with many other computers with the same operating system, giving advice on how to improve its stability and performance.

It is free, anonymous, transparent (meaning that you can examine exactly what data is retrieved before uploading it), very fast, you do not need administrator rights and it does not need to be installed on your computer.

It is based on the Internet community mechanism: a remark reported by one user will automatically be available to all other users. We therefore invite you to report any findings you may have.

Currently all Microsoft Windows operating systems as of Windows Millennium Edition or Windows Server 2000 are supported, provided the Microsoft .NET Framework 2.0 or higher is installed (standard available in Windows Vista and later). In the future other operating systems and mobile devices will be supported.
