Hey there! I’d like to disable USB devices from being installed on the computers in our network. Of course, it’s just storage devices I want to prevent from installing not mouses and keyboards. I don’t know how to do that and was unable to find the solution by googling. Do I need to write some kind of script perhaps? I would really appreciate if someone here could help me on this!

When you plug in a USB device the operating system start checking the device to determine if it's a storage device or not. If it finds that it’s a mass storage device it loads the appropriate driver and display the device in the Windows Explorer tree view. This is all done by using the usbstor.sys driver. To disable the using of USB storage drives you need to disable the usbstor.sys driver. This can be done trough Registry Editor.
You should find this reg key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTORLocate the Start value and set it to 'four'. The changes will apply without rebooting. I hope this helps you.
