Learn how to restore SOLIDWORKS thumbnails in Windows so that your thumbnails show the parts or assemblies themselves instead of that pesky icon.
Why is SOLIDWORKS opening a new session every time I launch a part from Windows Explorer? Well, there is this thing called SOLIDWORKS Launcher, you may have seen the name lurking somewhere around in your computer. This program is what decides which version of SOLIDWORKS to launch when a file is open. Usually, accidentally, SOLIDWORKS files get associated to be launched by SOLIDWORKS itself, not the SOLIDWORKS Launcher.
