Learn how to prevent unauthorized Screenshots.Remember all the way back when "Aero" was a new cool transparent UI Window style back in Windows Vista? Our cybersecurity team here in Austin does. I guess that's just how old we are?
Well... even today, all of our PCs in our Cybersecurity Lab still have this common Microsoft executable dwm.exe (Desktop Window Manager), and this safe .exe has been handling transparent windows all the way back to Windows Vista. So, what all does this Desktop Window Manager process do?
Dwm.exe handles tasks such as transparent windows, Aero effects, and high-resolution content. Dwm.exe also uses 3D hardware acceleration to render the desktop and manage graphical user interfaces aka the UI.
Dwm.exe should be completely safe on your PC, as long as it's signed by Microsoft. It's not malware, or a virus.
Below are 4 simple steps you can take to see if the dwm.exe process is safe or malware.

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
