PowerX PerfectSpeed is a software program developed by Raxco Software. The most common release is 2.00.118, with over 98% of all installations currently using this version. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The primary executable is named Rx2Engine.exe. The setup package generally installs about 16 files and is usually about 38.92 MB (40,811,389 bytes). The program is built using the Nokia Qt cross-platforms native C++ framework. Relative to the overall usage of those who have this installed, most are running it on Windows 7 (SP1). While about 83% of users of PowerX PerfectSpeed come from the United States, it is also popular in Japan.
