Windows Process Description:

The fast.exe process, also called the Super Fast User Switcher, belongs to the Microsoft Windows Operating system. It is registered under the Microsoft Company and is thus warranted a trustworthy file. The process fast.exe comes with the installation of the Windows XP PowerToys but maintenance of it in the system is optional.

The major function of the fast.exe process is to allow users to switch accounts quickly, without the need to use the Log In screen. The process fast.exe creates a hot key that enables switching between two user 'sessions' running in the PC. In some specific instances, the fast.exe process also allows two different people to sign on to the same computer simultaneously and swap between the two sign-ons with complete ease. Evidently, the fast.exe process is very efficient especially for users who have the need to switch frequently from one user account to another. To utilize this feature, the user should leave the fast.exe process running, or else it would not work at all. Removing the fast.exe process from the system when in use may pose adverse effect on the system.

As the program housing it (PowerToys) is for Windows XP only, the fast.exe process would only run on Windows XP. The general file size of this process on Windows XP is 49216 bytes. The fast.exe process is not a Windows system file and does not have visible window. This program may automatically start when Windows starts though it is not really required to run at start-up. User can manually initiate the process if he needs it.

Because the process fast.exe is usually found on the system, many spyware makers may attempt to disguise a malware and intentionally misspell it to look like the fast.exe file. The user should therefore make sure that the location of the fast.exe process is always checked. You can always rely on your Windows search options for this. Another practical action is to perform security check occasionally with the aid of anti-malware programs.
