Started after installing MSI nVidia drivers. Once you reboot, the installation will attempt to install two components, SW20.EXE and SW24.EXE. These executable files are the MSI D.O.T components.

From MSI Video cards installation
I do not know what it does but it appears to be from a driver update from MSI for my graphics card. I did a search from the Start button and it came up with two locations on my C drive. Both were the same size and date. One was in the System 32 folder and the other in the NVidia (MSI version) folder. I also have another file named sw24 that seems also to be from the MSI driver update.

they are MSI video driver components, google MSI D.O.T. for more info. "Installation is simple, just run the setup with the MSI driver. It will install the driver normally and then you can reboot. Once you reboot, the installation will attempt to install two components, SW20.EXE and SW24.EXE. These executable files are the MSI D.O.T components."

Best practices for resolving sw20 issues

A clean and tidy computer is the key requirement for avoiding problems with sw20. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the sw20.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
