Windows is based on hundreds if not thousands of background processes quietly running in the background. While these processes generally stay hidden from the users, at times, an occasional CPU spike or malware acting like one brings them into the spotlight.

In this article, we’re talking about the TwDsUiLaunch.exe process, what it does, and how you can get rid of it to save system resources.

What is the TwDsUiLaunch.exe process?

The process is a part of the M17A process that runs for the Brother Industries printing utility software developed by the Windows Hardware Compatibility Publisher. You’ll generally find it at this location.

C:\windows\twain_32\Brimm15a\Common\ 

The process helps the printing utility for Brother printers to run, print and diagnose any issues with the printer. This means that if you haven’t ever installed the utility on your PC, the process shouldn’t be there in the first place.

While it is a legitimate Windows process, there have been cases of malware impersonating the process for the most part. In such cases, you’ll notice sustained high CPU usage and system slowdowns owing to the process hogging up your PC’s resources.

If you determine the process is indeed a virus, here’s how you can remove it from your PC.

Step 1: Right-click the taskbar and find the process. Select it and click the End Task button at the bottom right.
