Prevent Installation Of Programs From Removable Media Source In Windows

Sometimes we use removable media such as CD-ROMs, floppy disks, and DVDs to install new programs to Windows. This is a common phenomenon and I think everyone using Windows is familiar to it. But what if anyone else installed some programs to your Windows without your permission, and which compromised your Windows? In such case your Windows installation may get ruined.

Using the concept of old saying that “prevention is better than cure“, if we configure Windows in such a way that it should not permit unknown media installation from removable source, then it will help us to safeguard our Windows from unknown installations, thus achieving high safety. In this article, I’ll show you the way to prevents users from installing programs from removable media. If a user tries to install a program from removable media, a message appears, stating that the feature cannot be found.
