📎 AI Summary:
The original poster, LostInHistory, is seeking a method to enable read-only access to USB devices on Windows—allowing copying data from the computer to the USB but preventing copying data back from USB to the computer. Neemobeer responds, noting that Windows 10 Pro users can configure Group Policy Objects (GPOs) to block write or total access to USB devices for security purposes but indicating that there is no free program readily available to achieve this specific "read-only" functionality. Overall, the discussion highlights a desire for fine-grained USB access control, with the consensus that current Windows tools may not fully support this feature without resorting to complex driver development.

Dear all,

I am trying to find a way how to block USB, but only read from USB. To be more specific, I want to allow copy from computer to USB, but deny copy from USB to computer.

Is there any way how to do it with Microsoft tools or free programs?

Thank you in advance

If you're using a Pro copy of Windows 10 you can enable GPOs to prevent write or all access to USB devices. This is meant to block users from taking data off of company computers. There is no free program to allow the amount of control you are asking for. What you're asking for would require creating some file system filter drivers.
