If you have already come across this article, you are probably looking for some information on this strange Dwm.exe process that is running in your Task Manager. Because this executable “eats up” quite a lot of memory and this number is unstable, the users look at it with suspicion and sometimes even speculate on it being an indicator of malware infection. In reality, there is no need to worry. This process is not malicious, and your computer is probably not infected with any viruses or potentially unwanted programs.
