How to Disable Copy and Paste in Windows: For Local Machines and VMs

Copy and paste functionality can be a major security risk.

It allows unauthorized data transfer between a local machine and a Virtual Machine (VM), potentially exposing sensitive information or violating security protocols. This is especially critical in environments where compliance with strict data protection policies is required.

The solution? Disable copy and paste for all users.

Whether you’re managing a team or ensuring your VM stays secure, this guide will walk you through step-by-step instructions for disabling clipboard redirection. You’ll learn how to block copy and paste for all users, including administrators, using the Windows Group Policy Editor.
