cFosSpeed v5.00


cFosSpeed v5.00 is a program developed by cFos Software GmbH, Bonn. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. 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 main program executable is cfosspeed.exe. The software installer includes 7 files and is usually about 7.91 MB (8,297,464 bytes). In comparison to the total number of users, most PCs are running the OS Windows 7 (SP1) as well as Windows 7. While about 20% of users of cFosSpeed come from Thailand, it is also popular in Vietnam and Poland.
